[R] Too strange that I cannot install several packages

[BR_email]

Hi Rers:
Is there anything I can check for as to why I cannot install several 
packages, i.e., sample, resample, resample_bootstrap, apply, sapply, ...?

The error message I get is:

>install.packages("sample") Installing package into 
‘C:/Users/BruceRatner/Documents/R/win-library/3.3’ (as ‘lib’ is 
unspecified) Warning in install.packages :
   package ‘sample’ is not available (for R version 3.3.3)


Thanks.
Bruce
