Hi,
I am not getting any errors.
data_chir <- read.table(text="N1_re N2_re N3_re
yes no no
no yes no
na yes yes
no na no",sep="",header=TRUE,stringsAsFactors=FALSE,na.strings="na")
library(reshape2)
melt(data_chir, measure.vars=c("N1_re", "N2_re"), var="zpd")
N3_re zpd value
1 no N1_re yes
2 no N1_re no
3 yes N1_re <NA>
4 no N1_re no
5 no N2_re no
6 no N2_re yes
7 yes N2_re yes
8 no N2_re <NA>
A.K.
