I have a dataframe with a numeric column. How can I substitute all zeros for NAs? I tried

 mtcars <- lapply(mtcars, function(v) {v[v==0] <- NA; v} )

and

 mtcars <- lapply(mtcars, function(v) {v[v==0] <- "NA"; v} )

but then the data are no longer numeric. Does anyone have a suggestion, please? Thank you.

Thank you so much! Apologies for the duplicate question. I had found the NA -> 0 question, but not this one. Thanks again. – Sylvia Rodriguez Jul 22 '19 at 09:45
