Subset
Hi,
Lets say this was a dataframe where I had two columns
a <- c("<0.1", NA, 0.3, 5, "Nil")
b <- c("<0.1", 1, 0.3, 5, "Nil")
And I just want to remove the rows from the dataframe where there were NAs
in the b column, what is the syntax for doing that?
Thanks in advance

a
[1] "<0.1" NA "0.3" "5" "Nil"
b <- as.numeric(a)
Warning message: NAs introduced by coercion
b
[1] NA NA 0.3 5.0 NA
b[! is.na(b)]
[1] 0.3 5.0 B.

Hi,
How do I extract just numbers from the following list:
a=c("<0.1",NA,0.3,5,Nil)
so I want to obtain: 0.3 and 5 from the above list
Thanks
