It is because you don't know whether you want it or not.
It is a bit more obvious with integer indexing, as in color[race]: if race is
NA you don't know what color to put in, but the result should be the same
length as race.
With logical indices, the behaviour is a bit annoying, but
c(1:3)[c(1,NA,3)]
[1] 1 NA 3

Good point! :-)

Hi
As OP has only about 250 files and in read_excel you cannot specify several
ranges at once, reading those values separately and concatenating them
together in one step seems to be the most efficient way. One probably could
design such function, but time spent on the function performing the
Hi Elham,
You are not giving us much to go on here.
Show us the commands that (a) confirm there are no NA's in the first column
of z
and (b) output a row of z that has an NA in the first column.
Here's how one might do this:
(a) sum(is.na(z[,1]))
(b) z[ match(TRUE, z[,8] %in% c("11","12","14")), ]
Hi all,
I have a simple problem. I get stuck in using the imported spss data (.sav)
using "read.spss".
I imported data (z) without any problem. After importing, the first column
doesn't contain any "NA". but when I choose a subset of it (like:
z[z[,8]=="11"|z[,8]=="12"|z[,8]=="14",]), lots of NA
>From your example, it appears you are reading in the same excel file for
each function to get a value. I would look at creating a function that
extracts what you need from each file all at once, rather than separate
reads.

Hi Eric,
There are a few mysteries in your request. As we don't know what "des"
is, it is difficult to see why it does not have the correct number of
dimensions. It looks like it should be an n x 6 matrix, but is that
what it really is and does the mlogit function expect such a matrix?

Hi Luis,
I had a quick look at the "diagram" package, which seems to accept
transition matrices. I don't have it installed, but the help pages are
fairly easy to follow and may do the job for you.

Are you sure that your command read values from respective cells?

Dear all,
I am trying to write an interface function (CBI function) in order to use the
bootstrapping function clusterboot() together with the clustering algorithm
kmodes(). See here:

I am trying to using the "paran" package in R for Horn's parallel analysis.
According to the "paran" manual, the highlighted yellow ought to be a numerical
matrix or data frame. It looks like this should be the file name. Is there
something that I need to do
