回答1:
And even shorter:
v <- na.omit(v)
回答2:
Try this:
new.v <- v[ !is.na( v ) ]
回答3:
Either is.na or na.omit are good enough for this situation
x <- c(1,NA,2,NA, 3) # a vector with NA
x[!is.na(x)] # a vector without NA
[1] 1 2 3
as.numeric(na.omit(x))
[1] 1 2 3
Actually as.numeric applied to na.omit is not necessary as you can tell from Dirk's answer :)
