I have s data set where 2 of the columns give the coded versions of the factors A and B. Factor A is coded with 1, 2, 3. Factor B is coded with 1,2. How do use the factor function to convert these variables into factors, and also use the labels= command to give them a more informative name? -- View this message in context: http://r.789695.n4.nabble.com/Factor-function-for-coded-numerical-values-tp4650483.html Sent from the R help mailing list archive at Nabble.com.

No example data is provided, but :
df <- data.frame(A=rep(1:2, 3), B=rep(1:3, 2))
df$A <- factor(df$A, levels=1:2, labels=c("a", "b"))
df$B <- factor(df$B, levels=1:3, labels=c("c", "d", "e"))

The question says that there is an experiement to investigate the effect on breathing rate when doing different types of exercise with wearing more clothes or less clothes (factor A, coded 1,2). The duration of exercise was 10min, 20min, 30min (factor B, coded 1,2,3). Could you give m anymore help? I tried using your R code but I couldn't get it to run. -- View this message in context: http://r.789695.n4.nabble.com/Factor-function-for-coded-numerical-values-tp4650483p4650883.html Sent from the R help mailing list archive at Nabble.com.
