Hi, have you (re)installed the most up-to-date version of the package?

Thanks for replying to my comment. I have upgraded my R to version 4.3.1 and updated all packages within R, but this error still occurred. Additionally, I downloaded the fect package fect_1.0.0.tar.gz from this link: (https://cran.r-project.org/web/packages/fect/index.html). I also made modifications to the src\fect.h file by adding #define arma_64bit_word 1 before #include , and included pkg_cppflags = -DARMA_64BIT_WORD=1 in both the src\Makevars and src\Makevars.win files. Afterward, I reinstalled the modified fect package. However, I am still encountering this error message. My data contains more than 700,000 observations, and 10 variables. My computer runs on a Windows operating system with 32GB of RAM. Thanks a lot!
