Re: [R] unable to remove NAs from a data frame

Hi You should consult either complete.cases function or to remove only rows in which are only NAs you could use something like (untested) df[!(colSums(is.na(df))==8),] Cheers Petr > -Original Message- > From: R-help On Behalf Of Ana Marija > Sent: Thursday, September 16, 2021 4:12 PM

Re: [R] How to globally convert NaN to NA in dataframe?

Hi Luigi. Weird. But maybe it is the desired behaviour of summary when calculating mean of numeric column full of NAs. See example dat <- data.frame(x=rep(NA, 110), y=rep(1, 110), z= rnorm(110)) # change all values in second column to NA dat[,2] <- NA # change some of them to NAN dat[5:6, 2:3]

Hi Please provide at least your code preferably with some data to reproduce this behaviour. I wonder if anybody could help you without such information. My wild guess is that you used set.seed(1234) some code the code used again in which case you have to expect different results. Cheers Pet
