Convert Yes-No indicators to TRUE-FALSE

Source: R/utilities.R
convert.YN2TF.Rd

Often True-False data is returned as a vector of Ys and Ns or 1s and 0s. These vectors often contain blanks or NAs that cannot, and should not, be converted into Falses. This function converts

  • "Y" –>> TRUE

  • "N" –>> FALSE

  • "Yes" –>> TRUE

  • "No" –>> FALSE

  • "1" –>> TRUE

  • "0" –>> FALSE

  • 1 –>> TRUE

  • 0 –>> FALSE

and leave blanks and NAs in the vector.

Usage

convert.YN2TF(YN.string)

Arguments

YN.string
