assertColumnName: Assert whether the required column names exist

In ribiosUtils: Utilities from and Interface to the Bioinfo-C (BIOS) Library

Description

The function calls matchColumnName internally to match the column names.

Usage

assertColumnName(data.frame.cols, reqCols, ignore.case = FALSE)

Arguments

data.frame.cols	column names of a data.frame. One can also provide a data.frame, which may however cause worse performance since the data.frame is copied
reqCols	required columns
ignore.case	logical, whether the case is considered

Value

If all required column names are present, their indices are returned *invisibly*. Otherwise an error message is printed.

Examples

myTestDf <- data.frame(HBV=1:3, VFB=0:2, BVB=4:6, FCB=2:4)
myFavTeams <- c("HBV", "BVB")
assertColumnName(myTestDf, myFavTeams)
myFavTeamsCase <- c("hbv", "bVb")
assertColumnName(myTestDf, myFavTeamsCase, ignore.case=TRUE)
