var	Variable to recode
from	Original scale (order of input needs to match desired scale)
to	Desired scale (order of input needs to match original scale). Defaults to integer scale starting from 1

Value

data.frame object

df <- data.frame(
      v1 = c("Strongly Disagree","Disagree", "Neutral"," Agree", "Strongly Agree"),
      v2 = c("Strongly Disagree","Disagree","Strongly Disagree","Disagree","Strongly Disagree"),
      v3 = c( "Neutral"," Agree", "Strongly Agree", "Neutral"," Agree")
      )

recode.multiple(df, var = c("v1","v2","v3"), from = c("Strongly Disagree","Disagree", "Neutral"," Agree", "Strongly Agree"))
recode.multiple(df, var = c("v1","v2","v3"), from = c("Strongly Disagree","Disagree", "Neutral"," Agree", "Strongly Agree"), to = c(10,20,30,40,50))
recode.multiple(df, var = c("v1","v2","v3"), from = c("Strongly Disagree","Disagree", "Neutral"," Agree", "Strongly Agree"), 
                to = c("ten", "twenty", "thirty", "forty", "fifty"),
