# AIM
# Check the class, type, mode and length of the data argument
# Mainly used to check the arguments of other functions
# Check also other kind of data parameters, is it a proportion? Is it type double but numbers without decimal part?
# If options == NULL, then at least class or type or mode or length argument must be non-null
# If options is non-null, then class, type and mode must be NULL, and length can be NULL or specified
# WARNINGS
# The function tests what is written in its arguments, even if what is written is incoherent. For instance, fun_check(data = factor(1), class = "factor", mode = "character") will return a problem, whatever the object tested in the data argument, because no object can be class "factor" and mode "character" (factors are class "factor" and mode "numeric")
# Since R >= 4.0.0, class(matrix()) returns "matrix" "array", and not "matrix" alone as before. However, use argument class = "matrix" to check for matrix object (of class "matrix" "array" in R >= 4.0.0) and use argument class = "array" to check for array object (of class "array" in R >= 4.0.0)
# ARGUMENTS
# data: object to test
# class: character string. Either one of the class() result (But see the warning section above) or "vector" or "ggplot2" (i.e., objects of class c("gg", "ggplot")) or NULL
# typeof: character string. Either one of the typeof() result or NULL
# mode: character string. Either one of the mode() result (for non-vector object) or NULL
# length: numeric value indicating the length of the object. Not considered if NULL
# prop: logical. Are the numeric values between 0 and 1 (proportion)? If TRUE, can be used alone, without considering class, etc.
# double.as.integer.allowed: logical. If TRUE, no error is reported if argument is set to typeof == "integer" or class == "integer", while the reality is typeof == "double" or class == "numeric" but the numbers strictly have zero as modulo (remainder of a division). This means that i <- 1, which is typeof(i) -> "double" is considered as integer with double.as.integer.allowed = TRUE. WARNING: data%%1 == 0 but not isTRUE(all.equal(data%%1, 0)) is used here because the argument checks for integers stored as double (does not check for decimal numbers that are approximate integers)
# options: a vector of character strings indicating all the possible option values for the data argument
# all.options.in.data: logical. If TRUE, all of the options must be present at least once in the data argument, and nothing else. If FALSE, some or all of the options must be present in the data argument, and nothing else. Ignored if options is NULL
# na.contain: logical. Can the data argument contain NA?
# neg.values: logical. Are negative numeric values authorized? Warning: only considered if set to FALSE, to check for non-negative values when class is set to "vector", "numeric", "matrix", "array", "data.frame", "table", or typeof is set to "double", "integer", or mode is set to "numeric". Ignored in other cases, notably with prop argument (which checks for values between 0 and 1 anyhow)
# print: logical. Print the error message if $problem is TRUE? Warning: set by default to FALSE, which facilitates the control of the error message output when using fun_check() inside functions. See the example section
# data.name: character string indicating the name of the object to test. If NULL, use what is assigned to the data argument for the returned message
# fun.name: character string indicating the name of the function checked (i.e., when fun_check() is used to check the arguments of this function). If non-null, the value of fun.name will be added into the message returned by fun_check()
# RETURN
# A list containing:
# $problem: logical. Is there any problem detected?
# $text: message indicating the details of the problem, or the absence of problem
# $object.name: value of the data.name argument (i.e., name of the checked object if provided, NULL otherwise)
# REQUIRED PACKAGES
# None
# REQUIRED FUNCTIONS FROM THE cute PACKAGE
# None
# EXAMPLE
# test <- matrix(1:3) ; fun_check(data = test, print = TRUE, class = "vector", mode = "numeric")
# see http
# DEBUGGING

# AIM
# Verify that local variables are not present in other environments, in order to avoid scope preference usage. The fun_secu() function checks by default the parent environment. This means that when used inside a function, it checks the local environment of this function. When used in the Global environment, it would check this environment
# ARGUMENTS
# pos: single integer indicating the position of the environment checked (argument n of parent.frame()). Value 1 means one step above the fun_secu() local environment. Thus, if fun_secu() is used in the working environment, with pos ==1, variables of the working env will be checked if they also exist in the above envs (Scope of R). If fun_secu() is used in a function, with pos ==1, variables presents in the local env of the function will be checked if they also exist in the above envs (Scope of R, which includes the working environment (Global env))
# name: single character string indicating the name of the function checked. If NULL, fun_secu() checks all the variables of the environment indicated by pos, as explained in the pos argument description. If non-null, fun_secu() checks all the variables presents in the local env of the function will be checked in the above envs (which includes the working environment (Global env)
# RETURN
# A character string of the local variables that match variables in the different environments of the R scope, or NULL if no match
# REQUIRED PACKAGES
# None
# REQUIRED FUNCTIONS FROM CUTE_LITTLE_R_FUNCTION
# fun_check()
# EXAMPLES
# fun_secu()
# fun_secu(pos = 2)
# mean <- 0 ; fun1 <- function(){sd <- 1 ; fun_secu(name = as.character(sys.calls()[[length(sys.calls())]]))} ; fun2 <- function(){cor <- 2 ; fun1()} ; fun1() ; fun2() ; rm(mean) # sys.calls() gives the the function name at top stack of the imbricated functions, sys.calls()[[length(sys.calls())]] the name of the just above function. This can also been used for the above function: as.character(sys.call(1))
# test.pos <- 2 ; mean <- 0 ; fun1 <- function(){sd <- 1 ; fun_secu(pos = test.pos, name = if(length(sys.calls()) >= test.pos){as.character(sys.calls()[[length(sys.calls()) + 1 - test.pos]])}else{search()[ (1:length(search()))[test.pos - length(sys.calls())]]})} ; fun2 <- function(){cor <- 2 ; fun1()} ; fun1() ; fun2() ; rm(mean) # for argument name, here is a way to have the name of the tested environment according to test.pos value

# AIM
# Provide a broad description of an object
# WARNINGS
# None
# ARGUMENTS
# data: object to analyse
# n: positive integer value indicating the n first number of elements to display per compartment of the output list (i.e., head(..., n)). Write NULL to return all the elements. Does not apply for the $STRUCTURE compartment output
# warn.print: logical. Print potential warnings at the end of the execution? If FALSE the warning messages are added in the output list as an additional compartment (or NULL if no message).
# RETURN
# A list containing information, depending on the class and type of data. The backbone is generally:
# $NAME: the name of the object
# $CLASS: class of the object (class() value)
# $TYPE: type of the object (typeof() value)
# $LENGTH: length of the object (length() value)
# $NA.NB: number of NA and NaN (only for type "logical", "integer", "double", "complex", "character" or "list")
# $HEAD: head of the object (head() value)
# $TAIL: tail of the object (tail() value)
# $DIMENSION: dimension (only for object with dimensions)
# $SUMMARY: object summary (summary() value)
# $STRUCTURE: object structure (str() value)
# $WARNING: warning messages (only if the warn.print argument is FALSE)
# If data is made of numerics, provide also:
# $INF.NB: number of Inf and -Inf
# $RANGE: range after removing Inf and NA
# $SUM: sum after removing Inf and NA
# $MEAN: mean after removing Inf and NA
# If data is a 2D object, provide also:
# $ROW_NAMES: row names
# $COL_NAMES: column names
# If data is a data frame, provide also:
# $COLUMN_TYPE: type of each column (typeof() value)
# If data is a list, provide also:
# $COMPARTMENT_NAMES: names of the comprtments
# $COMPARTMENT_TYPE: type of each compartment (typeof() value)
