#### DESCRIPTION

Cute Little R Functions contains 41 functions for R/RStudio that facilitate basic procedures in 1) object analysis, 2) object modification, 3) graphic handling and 4) log file management.

The function names are:

## Object analysis

fun_param_check() #### check class, type, length, etc., of objects
fun_object_info() #### recover object information
fun_1D_comp() #### comparison of two 1D datasets (vectors, factors, 1D tables)
fun_2D_comp() #### comparison of two 2D datasets (row & col names, dimensions, etc.)
fun_2D_head() #### head of the left or right of big 2D objects
fun_2D_tail() #### tail of the left or right of big 2D objects
fun_list_comp() #### comparison of two lists


## Object modification

fun_name_change() #### check a vector of character strings and modify any string if present in another vector
fun_dataframe_remodeling() #### remodeling a data frame to have column name as a qualitative values and vice-versa
fun_refactorization() #### remove classes that are not anymore present in factors or factor columns in data frames
fun_round() #### rounding number if decimal present
fun_90clock_matrix_rot() #### 90° clockwise matrix rotation
fun_num2color_mat() #### convert a numeric matrix into hexadecimal color matrix
fun_by_case_matrix_op() #### assemble several matrices with operation
fun_mat_inv() #### return the inverse of a square matrix
fun_mat_fill() #### fill the empty half part of a symmetric square matrix
fun_perm() #### progressively breaks a vector order
fun_perm_consec() #### progressively breaks a vector order

## Graphics management

fun_window_width_resizing() #### window width depending on classes to plot
fun_open_window() #### open a GUI or pdf graphic window
fun_prior_plot() #### set graph param before plotting
fun_scale() #### select nice numbers when setting breaks on an axis
fun_post_plot() #### set graph param after plotting
fun_close_specif_window() #### close specific graphic windows


## Standard graphics

fun_empty_graph() #### text to display for empty graphs


## gg graphics

fun_gg_palette() #### ggplot2 default color palette
fun_gg_just() #### ggplot2 justification of the axis labeling, depending on angle
fun_gg_scatter() #### ggplot2 scatterplot + lines (up to 6 overlays totally)
fun_gg_bar_mean() #### ggplot2 mean barplot + overlaid dots if required
fun_gg_boxplot() #### ggplot2 boxplot + background dots if required
fun_gg_bar_prop() #### ggplot2 proportion barplot
fun_gg_strip() #### ggplot2 stripchart + mean/median
fun_gg_violin() #### ggplot2 violins
fun_gg_line() #### ggplot2 lines + background dots and error bars
fun_gg_heatmap() #### ggplot2 heatmap + overlaid mask if required
fun_gg_empty_graph() #### text to display for empty graphs


## Graphic extraction

fun_var_trim_display() #### display values from a quantitative variable and trim according to defined cut-offs
fun_segmentation() #### segment a dot cloud on a scatterplot and define the dots from another cloud outside the segmentation


## Import

fun_pack_import() #### check if R packages are present and import into the working environment
fun_python_pack_import() #### check if python packages are present


## Exporting results (text & tables)

fun_export_data() #### print string or data object into output file

#### HOW TO USE IT

1) Download the desired Tagged version, never the current master, at https://gitlab.pasteur.fr/gmillot/cute_little_R_functions/-/tags

2) Directly source the cute_little_R_functions.R into R/RStudio to have the functions available in the working environment, using for instance source("https://gitlab.pasteur.fr/gmillot/cute_little_R_functions/raw/v6.0.0/cute_little_R_functions.R")

Description of the functions is at the beginning of the function body. To obtain it:

	Either read the cute_little_functions.docx (or open the cute_little_R_functions.R file).
	
	Or in the R/RStudio console, type the name of the function without brackets. Example : fun_object_info.




#### FILE DESCRIPTIONS

cute_little_R_functions.R	file that has to be sourced
cute_little_R_functions.docx	file that facilitate reading of the function description
examples_alone.txt	compile all the examples of the functions into a single file
