[R] subset data frame by variable with missing value

[arun]

Hi,
YOu could also use:
set.seed(5)
dat1<-data.frame(col1=sample(c(1:4,NA),10,replace=TRUE),col2=runif(10,0,1))
 dat1[!complete.cases(dat1),]
#  col1      col2
#3   NA 0.3184040
#8   NA 0.8878698
#9   NA 0.5549226
A.K.

Subject: [R] subset data frame by variable with missing value

Hello,

I have a variable in a data frame that contains NA values. I just want to
subset so that I get the obs where that variable is missing.
In SAS I would do:

data missing;
  set test;
  if myvalue=' ';
run;

How can I perform this simple task in R?

Thanks in advance for your help.
