Wow, you are quite confused! Have you gone through any basic R
tutorials (there are many good ones on the web), as it sure looks like
you have not and therefore have almost no idea how to use R. If that
is the case, it is unlikely that this list (or R!) is going to be much
use to you.
Anyway, appl
Thank you.

What makes you think " apply' does not work in R 3.2.2"?

Hello,I quite understand that apply is doing what it is supposed to do. I
actually found that example online. However, "apply" package is not compatible
with R 3.2.2 and as a result, I could not use the code. That is why I am asking
for an alternative to "apply" that can be used to do the same t
Olu,
I think you may have misread what na.rm is supposed to do. I think you are
getting the correct value. If you want the vectors that contain NA values to be
evaluated to NA then you will need to set na.rm to FALSE (which is the default
for prod()).
prod(c(7, 2, NA), na.rm = TRUE)
[1] 14
pro
Df.1$D looks correct to me. For example, in the third row, 7*2=14 is
correct with the NA removed.
