[R] Question abt 'factanal' function
Hi, I tried to run 'factanal' function for Factor Analysis, but failed to get results. The error message was following, Error in factanal(data, factors = 3, rotation = varimax) : unable to optimize from this starting value I searched for the solution of this error, and one said putting 'control=list(trace=T)' in the argument as option, but it also failed. looks like no way for it on my own. I doubted that high correlation btw observed variables in the original data, so removed some variables with high correlations (1~3, 19, 23~33). After that, I ran it , but also couldn't get any output. If you respond to my question, it will a big help for me .

[R] Problem in installing package ggplot2
Hi.. After I upgraded R from 3.1 to 3.11, I stuck with problem in installing 'ggplot2' package The error message was; Error in loadNamespace(j - i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]) : there is no package called âRcppâ Error: package or namespace load failed for âggplot2â I tried to find out resolution on the web.. and most people recommend following; install.packages(ggplot2,dependencies=T) However, it didn't work, either.. it's so confusing. I should use this package ASAP.. so, hope you guys give me a clear answer.
