Thank you Bert for this clarification. It is indeed an important point.

Hello,
You could do
ds_test[is.na(ds_test$var1), ] <- 0 # note the comma
or, more generally,
ds_test[] <- lapply(ds_test, function(x) {x[is.na(x)] <- 0; x})
Hope this helps,

Sorry, Ivan, your statement is incorrect:
"When you use a single bracket on a list with only one argument in
between, then R extracts "elements", i.e. columns in the case of a
data.frame. This explains your errors. "
e.g.
> ex <- data.frame(a = 1:3, b = letters[1:3])
> a <- 1:3
> identical(ex[1
My statement "Using a single bracket '[' on a data.frame does the same
as for matrices: you need to specify rows and columns" was not correct.
When you use a single bracket on a list with only one argument in
between, then R extracts "elements", i.e. columns in the case of a
data.frame. This
Dear Georg,
You need to learn a bit more about the subsetting methods, depending on
the object structure you're trying to subset.
More specifically, when you run this: ds_test[is.na(ds_test$var1)]
you get this error: "Error in `[.data.frame`(ds_test,
is.na(ds_test$var1)) : undefined columns s
Suggestion: figure out the correct extraction syntax first. One you do that
replacement will be easy.
See ?Extract for all the messy details.

Hi All,
I would like to recode my NAs to 0. Using a single vector everything is
fine.
But if I use a data.frame things go wrong:
-- cut --
var1 <- c(1:3, NA, 5:7, NA, 9:10)
var2 <- c(1:3, NA, 5:7, NA, 9:10)
ds_test <-
data.frame(var1, var2)
test <- var1
test[is.na(test)] <- 0
test # NA rec
18 matches
