# AIM
# if the data frame is made of numeric columns, a new data frame is created, with the 1st column gathering all the numeric values, and the 2nd column being the name of the columns of the initial data frame. If row names were present in the initial data frame, then a new ini_rowname column is added with the names of the rows

 
# If the data frame is made of one numeric column and one character or factor column, a new data frame is created, with the new columns corresponding to the split numeric values (according to the character column). NA are added a the end of each column to have the same number of rows. BEWARE: in such data frame, rows are not individuals. This means that in the example below, values 10 and 20 are associated on the same row but that means nothing in term of association

 

# ARGUMENTS

# AIM
# round a vector of values, if decimal, with the desired number of decimal digits after the decimal leading zeros
# WARNINGS
# Work well with numbers as character strings, but not always with numerical numbers because of the floating point
# Numeric values are really truncated from a part of their decimal digits, whatever options(digits) settings
# See ?.Machine or https://stackoverflow.com/questions/5173692/how-to-return-number-of-decimal-places-in-r, with the interexting formula: abs(x - round(x)) > .Machine$double.eps^0.5
# ARGUMENTS
# data: a vector of numbers (numeric or character mode)
# dec.nb: number of required decimal digits
# after.lead.zero: logical. If FALSE, rounding is performed for all the decimal numbers, whatever the leading zeros (e.g., 0.123 -> 0.12 and 0.00128 -> 0.00). If TRUE, dec.nb are taken after the leading zeros (e.g., 0.123 -> 0.12 and 0.00128 -> 0.0013)

# AIM
# assemble several matrices of same dimensions by performing by case operation. For instance add the value of all the case 1 (row1 & column1) of the matrices and put it in the case 1 of a new matrix M, add the value of all the case 2 (row2 & column1) of the matrices and put it in the case 2 of a new matrix M, etc.
 
# c: case
# i: row number
# j: column number
# k: matrix number
# z: number of matrices
# ARGUMENTS:
# mat.list: list of matrices
# kind.of.operation: either "+" (by case addition), "-" (by case subtraction) or "*" (by case multiplication)

######## fun_permut() #### progressively breaks a vector order


fun_permut <- function(
data1, 
data2 = NULL, 
n = NULL, 
seed = NULL,

text.print = "",

# AIM
# reorder the elements of the data1 vector by flipping 2 randomly selected  consecutive positions either:
# 1) n times (when n is precised) or
# 2) until the correlation between data1 and data2 decreases down to the cor.limit (0.2 by default). See cor.limit below to deal with negative correlations
# Example of consecutive position flipping: ABCD -> BACD -> BADC, etc.
# designed for discrete values, but worls also for continuous values
# WARNINGS
# see # https://www.r-bloggers.com/strategies-to-speedup-r-code/ for code speedup
# the random switch of non consecutive positions (ABCD -> DBCA for instance) does not work very well as the correlation is quickly obtained but the initial vector structure is mainly kept (no much order). Ths code would be: pos <- ini.pos[1:2] ; pos <- sample.int(n = n , size = 2, replace = FALSE) ; tempo.pos[pos] <- tempo.pos[rev(pos)]
# ARGUMENTS
# data1: a vector of at least 2 elements. Must be numeric if data2 is specified
# data2: a numeric vector of same length as data1
# n: number of times "flipping 2 randomly selected consecutive positions". Ignored if data2 is specified
# seed: integer number used by set.seed(). Write NULL if random result is required, an integer otherwise. BEWARE: if not NULL, fun_permut() will systematically return the same result when the other parameters keep the same settings
# print.count: interger value. Print a working progress message every print.count during loops. BEWARE: can increase substentially the time to complete the process using a small value, like 10 for instance. Use Inf is no loop message desired
# text.print: optional message to add to the working progress message every print.count loop
# cor.method: correlation method. Either "pearson", "kendall" or "spearman". Ignored if data2 is not specified
# cor.limit: a correlation limit (between 0 and 1). Ignored if data2 is not specified. Compute the correlation between data1 and data2, permute the data1 values, and stop the permutation process when the correlation between data1 and data2 decreases down below the cor limit value (0.2 by default). If cor(data1, data2) is negative, then -cor.limit is used and the process stops until the correlation between data1 and data2 increases up over cor.limit (-0.2 by default). BEWARE: write a positive cor.limit even if cor(data1, data2) is known to be negative. The function will automatically uses -cor.limit. If the initial correlation is already below cor.limit (positive correlation) or over -cor.limit (negative correlation), then the data1 value positions are completely randomized (correlation between data1 and data2 is expected to be 0)
