I\'m trying to calculate the mean and standard deviation of several columns (except the first column) in a data.frame with NA
values.
I\'ve tried
sapply(df, function(cl) list(means=mean(cl,na.rm=TRUE), sds=sd(cl,na.rm=TRUE)))
col1 col2 col3 col4 col5
means 3 8 12.5 18.25 22.5
sds 1.581139 1.581139 1.290994 1.707825 1.290994
as.data.frame( t(sapply(df, function(cl) list(means=mean(cl,na.rm=TRUE),
sds=sd(cl,na.rm=TRUE))) ))
means sds
col1 3 1.581139
col2 8 1.581139
col3 12.5 1.290994
col4 18.25 1.707825
col5 22.5 1.290994
