I have installed "reshape2" package but when I run it I get this error message " package or namespace load failed for ‘reshape2’ in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]): there is no package called ‘stringi’"

The fix for that specific problem is to run install.packages("stringi"). That will likely lead to another similar error for a different package when you try to load reshape2 again. What command did you run to install reshape2? What version of R are you using?

sidenote : there may be a usecase need for reshape2, if you inherited legacy code that relied on it
but if you are going to new work, its recommended that you dont use reshape2; the tidyr component of tidyverse has superceded it.

I used the command "install.packages("reshape2")"
I'm using R version 4.3.2

Yes, you are right. I'm using some legacy codes. Do I need to install tidyverse package?

6

it depends if you only want to run the old code as it was, or if you want to do work to modernise it.

Have you tried installing stringi?
