reverse code variables

Hi everyone,

I'm currently working on the following project for the empirical project 11. They even gave us the codes but I have the following issue when I write this part:

                   "scepticism_6", "scepticism_7")])$total$std.alpha
psych::alpha(WTP[c("cog_1", "cog_2", "cog_3", 
                   "cog_4", "cog_5", "cog_6")])$total$std.alpha
psych::alpha(WTP[c("PN_1", "PN_2", "PN_3", 
                   "PN_4", "PN_6", "PN_7")])$total$std.alpha

and the error says:
Error in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]) :
there is no package called ‘mnormt’

I'm a beginner in using R, so I don't really know how to fix most of the errors.

Thank you!

You are missing this package dependency, you just have to install it.


Have in mind that mnormt requires R >= 4.0.0 so you might have to update R as well.

Ah okay!

Thank you so much!
