better way to replace missing values with zero
...like below--where ever they may be--but some of the column classes are non-numeric so I get an error: > dim(temp) [1] 699 313 > temp[is.na(temp)] <- 0 Error in as.Date.default(value) : do not know how to convert 'value' to class "Date" > So I have to use more conveluted code: for (k in c(1:ncol(temp))) { if (class(temp[, k])=="numeric") { temp[, k][is.na(temp[, k])] <- 0 } } This is much more code and requires a for loop. Can anyone please show me a better way? Thanks, Roger...
