I build my rpackage
with Rstudio, everything goes fine. When use check
button in rstudio
, it gives me some warnings, listed below:
* checking whether package 'rpackage' can be installed ... WARNING
Found the following significant warnings:
Warning: package 'e1071' was built under R version 3.2.4

How can I remove these warnings?

That's likely your R version is out of date: the R version used (3.2.4
) to build these packages is ahead of yours, and so a warning is returned.
You can check your current version either in the preamble when you launch a new session or by typing R.version
.
Most of the time it has no practical consequences (for small gaps between R versions), but: i) the function you use may have been affected by version change and ii) it's a good idea to have the last R stable version.
