pcutils

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

The HTML documentation of the latest version is available at Github page.

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")

Little tools

• lib_ps, del_ps can library or detach packages gracefully

• dabiao print a message dabiao("Message",char = "😀",n = 20): 😀😀😀😀😀😀Message😀😀😀😀😀😀

• 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
