Currently I am estimating IV regresssion with panel data. I thought, fixest packages is the good fit for the analysis. After it is showing some warning when I installed, I can't recall the library.
The error is
library(fixest) Error: package or namespace load failed for ‘fixest’: .onAttach failed in attachNamespace() for 'fixest', details: call: read.table(file = file, header = header, sep = sep, quote = quote, error: empty beginning of file
I thought of using plm package instead. I want clustered standard error, and as I understood from the documentation it doesn't have option as fixest has.
