Recoding missing values Regularly, missing data isn't coded as NA in datasets. In SPSS for example, missing values are often represented by the value 99. num.vec <- c(1, 2, 3, 99, 5) num.vec ## [1] 1 2 3 99 5 It is possible to directly assign NA using subsetting num.vec[num.vec == 99]...

To coerce a variable to a logical use the as.logical() function. > x <- 2 > z <- x > 4 > z [1] FALSE > class(x) [1] "numeric" > as.logical(2) [1] TRUE When applying as.numeric() to a logical, a double will be returned. NA is a logical value and a logical ...
