rminmax_df: Row-wise min-max

In alorchhota/spice: SPICE: Spanning tree based inference of co-expression networks

Description

This function finds row-wise min-max values in two columns of a given dataframe.

Usage

rminmax_df(df, col1 = colnames(df)[1], col2 = colnames(df)[2], unique = F)

Arguments

df	data frame with at least two columns.
col1	character. must be a column of df.
col2	character. must be a column of df.
unique	if TRUE, duplicate rows are removed from the returned data frame.

Details

Given a data frame (df) and two of its columns (col1 and col2), this function re-arranges the content of these columns so that the first and second column contains the rowwise minimum and the rowwise maximum of the two columns, respectively. Factor values are sorted by their labels. If there are other columns in df, those columns remain unchanged. if unique = TRUE, the output data frame contains only unique rows.

Note: both columns must have same type of data.

Value

A data frame with the same set of columns as df.

Examples

my_df = data.frame(A=c(1,5,2,9,1), B = LETTERS[1:5], C=c(1,3,5,7,9))
# my_minmax_df = rminmax_df(my_df, col1='A', col2 = 'C')
