Hi all,
When I called arrayIndex(20:23, dim=c(4,3,3)), it says "Error: could not
find function "arrayIndex"in R". So I called ls("package:utils") to see the
functions inside:
[1] "?"
[2] "adist"
[3] "alarm"
[4] "apropos"
[5] "aregexec"
[6] "argsAnywhere"
[7] "arrangeWindows"
[8] "as.person"
I'm only listing the first 8 results because it has a total of 223 listed
functions,which is too long.
When I looked up utils package, This page
http://astrostatistics.psu.edu/su07/R/html/utils/html/00Index.html shows
exactly the same result, but this page
http://rss.acs.unt.edu/Rdoc/library/R.utils/html/00Index.html shows a
different list and none of the functions listed( such as arrayIndex,
bunzip, doCall) is recognized by R:No documentation for arrayIndex in
specified packages and libraries: you could try ??arrayIndex. So I'm
just confused:
1. why does utils package have two different lists of functions?
2. If arrayIndex() comes with utils package, why can't R recognize it ? If
it doesn't come with utils, then what package should I install to use
functions such as arrayIndex, bunzip, doCall,etc. ?
Thanks!
