Changing column types with dplyr

Question

I need some help tidying my data. I\'m trying to convert some integers to factors (but not all integers to factors). I think I can do with selecting the variables in question

Answer 1

Honestly, I'd do it like this:

library(dplyr)

df = data.frame("LOC_ID" = c(1,2,3,4),
                "STRS" = c("a","b","c","d"),
                "UPC_CDE" = c(813,814,815,816))

df$LOC_ID = as.factor(df$LOC_ID)
df$UPC_CDE = as.factor(df$UPC_CDE)
