Problems to load packages in memory in RStudio

Hi,

I´m trying to use the following packages in RStudio: ggplot2, dplyr, tidyverse.

I have no problems wtih the instalation
install.packages("ggplot2")
install.packages("dplyr")
install.packages("tidyverse")

And I can find the propers folders created in the R directory but when I try to charge in memory the package I get this error:

library(ggplot2)
Error: package or namespace load failed for ‘ggplot2’ in readRDS(nsInfoFilePath):
formato de entrada desconocido.

Any help, please ?
