Based on the OP's submission I pasted the following into R and tried to run it.
Here is what I think was posted (comments removed):
my_data <- 1:5
my_data
my_subset_criteria <- c( F, F, T, NA, NA) my_subset_criteria
equals TRUE my_data[my_subset_criteria == T]
my_subset_criteria == T)
Assuming that this is the right code I tried to run it.
The third line " my_subset_criteria <- c( F, F, T, NA, NA) my_subset_criteria"
returns an error.
As it should. You put two commands on the same line with no correct
separator:Either of these should succeed:
my_subset_criteria <- c( F, F, T, NA, NA)
my_subset_criteria
# OR
my_subset_criteria <- c( F, F, T, NA, NA) ; my_subset_criteria
(The original poster had the correct syntax.)

Mmmm, ESP on the blink.
WHAT error? from which line of code?
BTW see The R Inferno, section 8.2.32

I noticed that I get different results when subsetting using subset, compared to
subsetting using "brackets" when the subset criteria have NA's.
Here's an example
#START OF EXAMPLE
my_data <- 1:5
my_data
my_subset_criteria <- c( F, F, T, NA, NA) my_subset_criteria
#subsetting using subset returns the data where my_subset_criteria
equals TRUE my_data[my_subset_criteria == T]
#subsetting using brackets returns the data where my_subset_criteria
equals TRUE, and also NA where my_subset_criteria is NA subset(my_data,
my_subset_criteria == T)
#END OF EXAMPLE
This behavior is also mentioned here

Q. Is this the intended behavior when subsetting with brackets?
Thank you!
