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 recoded OK
# First try
ds_test[is.na(ds_test$var1)] <- 0 # duplicate subscripts WRONG
# Second try
ds_test[is.na("var1")] <- 0
ds_test$var1 # not recoded WRONG
# Third try: to me the most intuitive approach
is.na(ds_test["var1"]) <- 0 # attempt to select less than one element in
integerOneIndex WRONG
# Fourth try
ds_test[is.na(var1)] <- 0 # duplicate subscripts for columns WRONG
-- cut --
How can I do it correctly?
Where could I have found something about it?
Kind regards
Georg
