Hi i am trying to install the package stringr in my R.
i tried following:
install.packages("stringr")
install.packages("stringr",dependencies = TRUE, repos = "http://cran.us.r-project.org")
install.packages("stringr", dependencies=TRUE, INSTALL_opts = c('--no-lock'))
it still give me the error:
Package ‘stringr’ version 1.2.0 cannot be unloaded:
Error in unloadNamespace(package) : namespace ‘stringr’ is imported by ‘bibtex’ so cannot be unloaded
how can i fix this?
Thanks!
