Hi @mrchypark ,

The problem is the location you provide for sys_dic.

> pos(tar, sys_dic = "c:/mecab")
Exception: 
list()
> pos(tar)
$`안녕하세요 저는 박찬엽 입니다.`
[1] "안녕/NNG"      "하/XSV"        "세요/EP+EF"    "저/NP"         "는/JX"         "박찬엽/NNP"    "입니다/VCP+EF" "./SF"         

> pos(tar, sys_dic = "c:/mecab/mecab-ko-dic/")
$`안녕하세요 저는 박찬엽 입니다.`
[1] "안녕/NNG"      "하/XSV"        "세요/EP+EF"    "저/NP"         "는/JX"         "박찬엽/NNP"    "입니다/VCP+EF" "./SF" 

You should put the location for the MeCab-dic (or MeCab-ko-dic, in this case).

Thanks!

Do you have any plan to manage sys_dic location with environmental variables?
