bom dia,
mesmo depois de executar o R como administrador tenho alguns problemas para instalar alguns pacotes no R (nlme e lubridate entre outros).  Alguma dica para solução deste problema? 

 

> install.packages("nlme")

Installing package into 'C:/Users/andreoliveira/Documents/R/win-library/3.6'
(as 'lib' is unspecified)

package 'nlme' successfully unpacked and MD5 sums checked
Warning: cannot remove prior installation of package 'nlme'

The downloaded binary packages are in
C:\Users\andreoliveira\AppData\Local\Temp\RtmpMH69CO\downloaded_packages
Warning message:

att,.
