pcutils

pcutils is a package that contains some useful functions for me, it offers a range of utilities and functions for everyday programming tasks.

Installation

The stable version is available on CRAN:

install.packages("pcutils")

Or you can install the development version of pcutils from GitHub with:

# install.packages("devtools")
devtools::install_github("Asa12138/pcutils")

• copy_vector help to copy a vector, like datapasta package; copy_df help to copy a dataframe

• change_fac_lev can change a factor levels; tidai can replace a vector by named vector

• update_param update a parameter in a function

• sanxian print a three-line table

• grepl.data.frame and gsub.data.frame do grepl and gsub on a dataframe.

for file

• read.file read some special format files

• trans_format convert file format like jpg, png, svg, pdf, html…

• read_fasta and write_fasta read and write fasta file

for web

Statistics

data preprocessing

• remove.outliers remove the outliers

• count2 imitate the uniq -c in shell

• hebing group your dataframe; guolv filter a dataframe; rm_low remove low frequency

• trans transfer your data

• mmscale do a scale specifying the min and max

• strsplit2 is better than strsplit for me; t2 is better than t for me

• explode expand a column in dataframe; squash squash a dataframe

• pre_number_str prepare a number string

statistical test

• twotest do a two-group test and multitest do a multi-group test; group_test performs multiple mean comparisons for a data.frame

• fittest test a vector fit which distribution

• toXY transfer geographical latitude and longitude to XY(m)

• lm_coefficients get the coefficients of a linear model; multireg fit a multiple linear model

Visualization

utils for plot

• rgb2code convert between r,g,b and color code; is.ggplot.color judge a right color; add_alpha add a alpha for a color

• plotpdf, plotgif print pdf or gif for a plot list

• get_cols generate n colors based on a palette; scale_fill_pc and scale_color_pc are scales for ggplot

• add_theme generate a mytheme object for ggplot

• legend_size resize the legend for a ggplot; ggplot_lim get the x-y limits for a ggplot
