Error in subset(findings, SUBJECTSID == SUBJECTS1$SUBJECTSID, select =
c(SUBJECTSID, :
object "findings" not found
Gives me an error. Strange, is it possible that I do not have SUBJECTS1 or
SUBJECTSID on my computer?
however
subset(iris, subset=iris$Species=="virginica", select=c("Sepal.Length",
"Petal.Length"))
Sepal.Length Petal.Length
101 6.3 6.0
102 5.8 5.1
103 7.1 5.9
104 6.3 5.6
105 6.5 5.8
106 7.6 6.6
works as expected
Or you can use
iris[iris$Species=="virginica", c(1,3)]
to get same result without using subset.
