Remove NAs from one column

[nviet]

(See screenshot) In the twin column, I'm trying to remove NAs. Although, I don't all NAs removed from the data set because there would not be anything left, because its survey data. So how would i accomplish this?

FYI: complete.cases does not work. It removes everything

Column with "2s" in it, is the twin column

[CALUM_POLWART]

Lots of ways to do this.

In base R:

myData <- myData[!is.na(myData$twin),]

In tidyverse:

require(tidyverse)

myData %>%
    filter (!is.na(twin)) -> myData

Bear in mind - both are over writing your dataset

is.na() - means the value is NA
! - means IS NOT.

so !is.na() means IS NOT NA

Awesome. Work perfect. Thanks
