[R-sig-Geo] Selecting a range of longitude and latitudes

[Vijay Lulla]

It appears that you might have mistakenly typed cbind(103:110, 3:16)
instead of cbind(103:116, 3:16).  Regardless, the warning is telling you
that the vectors were of unequal lengths and there was some recycling.  You
can learn about recycling rule from searching "recycling rule in R" and
also from R's Introduction manual at
https://cran.r-project.org/doc/manuals/r-release/R-intro.html#The-recycling-rule
.
