numberForLevels: numberForLevels

In lwTools/agriTrf: Agricultural Transformation Package: data management, depiction and modelling

Description

numberForLevels takes as input a column (dfCol), a character vector containing the levels of the column, and a numeric vector containing the numbers to be assigned to these levels and returns a one column data.frame object with each entry of the original column replaced by the number corresponding to the respective level.

Usage

numberForLevels(dfCol, vec1, vec2)

Arguments

dfCol	a column of a data.frame object whose levels have to be numbered. Note that this is not a character string but the column itself (refer to examples)
vec1	a vector of class character containing the levels in column dfCol
vec2	a vector containing the values to be assigned to each level in vec1.

Value

numberForLevels returns a data.frame object containing one column where each entry of the original column is replaced by the number assigned for the respective level. NA column entries stay unaffected.

Examples

numberForLevels(table[,"col1"], c("a","b","c"),c(1:3))
numberForLevels(warpbreaks[,"tension"],c("L","M","H"),c(1,5,10))
numberForLevels(iris[,"Species"],c("setosa", "versicolor", "virginica"),c(101,102,103))
