R - remove rows with NAs in data.frame
How can I quickly remove "rows" in a dataframe with a NA value in one of the columns?
So
x1 x2
[1,] 1 100
[2,] 2 NA
[3,] 3 300
[4,] NA 400
[5,] 5 500
should result in:
x1 x2
[1,] 1 100
[3,] 3 300
[5,] 5 500
This question is related to
r
dat <- data.frame(x1 = c(1,2,3, NA, 5), x2 = c(100, NA, 300, 400, 500))
na.omit(dat)
x1 x2
1 1 100
3 3 300
5 5 500
