The goal of handyFunctions is to get rid of the barrier to deal with non-standard data.frame format for R newbies, especially the user in bioinformatics data analysis. Besides, there are also some required plot functions for downstream analysis of dataset generated from vcftools and plink.
You can install the development version of handyFunctions like so:
## Clone it from github and install it locally
git clone https://github.com/LuffyLouis/handyFunctions.git
## OR
## Install it in R
remotes::install_github("LuffyLouis/handyFunctions")handyFunctionspackage contain three main sections,
including ReformatDataframe, InteractDataframe, and Post-VCF. There are
some basic examples which show you how to solve common problems in data
analysis:
This section is designed to reformat data.frame with odd colnames, rownames, or even inappropriate dtypes for each columns.
Based on the following example unifyDataframe function,
you can change the formats of raw data.frame to what you want.
Especially for the dtypes in data.frame, you can set
custom=FALSE for automatically changing into appropriate
dtypes.

#> 6 Xiaoyu Chen female 74 89Note: due to the separation supporting regEx, please
use the "[.][.]" for reformatting people
data.frame.
The InteractDataframe section is designed for
interaction between two data.frame or one data.frame and another
vector.
Sometimes, we often find it fuzzy and tedious while we’d like to
merge two data.frame with different colnames. Therefore,
mergeCustom function may be the better solution to get it
rid of.
