drm() function + inslall "drc" issue

[Nata]

Hi, everyone,

Have an issue: not working drm function for me:
?drm()

Error in .helpForCall(topicExpr, parent.frame()) :
no methods for ‘drm’ and no documentation for it as a function

Here is drm() function description: drm package - RDocumentation

What i have tried already, based on search:

1. install.packages("drm")
   Warning in install.packages :
   package ‘drm’ is not available (for R version 3.6.1)

2. install.packages("drc")

also installing the dependency ‘car’....

Any advises for the R-Studio beginner would be highly appreciated !

install.packages("drc")
also installing the dependency ‘car’

There is a binary version available but the source version is later:

@Nata

install.packages("drm")
Warning in install.packages :
package ‘drm’ is not available (for R version 3.6.1)

The drm package hasn't been on CRAN since at least 8 years ago and it doesn't seem to be maintained any more but you can still install it from the GitHub CRAN mirror.

remotes::install_github("cran/drm")

@Nata

Error in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]) :
there is no package called 'foreign'

This other error message is telling you that you are missing a package dependency and you need to install it, the problem is that the foreing package requires R >= 4.0.0 so you need to update your R version to be able to install this package.

Thanks @andresrcs for the prompt response. it works!
