Error with RcppMeCab, Exception: list()

[sdkpark]

Hello,

I have used RcppMeCab very well, but the error has occurred since I formatted my PC and reinstalled all of the latest versions of R and Rstudio.

When pos() is used with the following code,

test <- "이것은 비타500입니다." pos(iconv(test, to = "UTF-8"))

I found the error message like

Exception: list()

Here is the information from R and R studio that I am using.

R version: 4.0.3 R Studio version: Version 1.4.1103

@sdkpark Hi, this Exception occurs when mecab and mecab-dict is not installed in desired location (e.g. C:\mecab).

Can you confirm that two binaries are located in that directory?

Thanks for the prompt reply. I checked that user-custom.csv file is located under "C:\mecab\mecab-ko-dic".

@sdkpark If you want to use user dictionary, please compile it to .dic using mecab-dict-index.exe.

Exception error means that RcppMecab cannot initialize mecab binaries, especially mecabrc and other files which belong to mecab-dict. Please check that mecab-ko-dic-msvc files (not your user dictionary) are in correct locations.

Thank you very much for your advice. It is found that the issue is related with the security issue of the C drive.
It looks like that security permissions must have been set for users after formatting the computer as shown by following figure.

Mecab-ko-dic-msvc files were in correct locations, but it could not be accessed. It was solved.
