r - How to interpret error in write(mydata, "mydata.csv")? "List" cannot be handeled by "cat"? -


seems ran similar problem, here. however, jacob's question (from 2 years ago) still unanswered. , also, context there little different mine:

so trying export dataframe .csv file works fine. time, however, ran following error message:

write(mydata, "mydata.csv")  #error message: error in cat(x, file = file, sep = c(rep.int(sep, ncolumns - 1), "\n"), : argument 1 (type 'list') cannot handled 'cat'

now won't copy , paste head(mydata) returns, because dataframe relatively big. there seems nothing wrong data , variables, can work with them normally. thing cannot export them .csv file (or other format).

help?*

*probably stupid , have overlooked something...

chi pak's comment above right. address problem of saving data frame csv, use write.csv instead of write.

to address question, error message arose because write totally different breed of animal write.csv. if read file ?write, described wrapper concatenate function cat, expects data written out in form of atomic vector (or resulting names()).

a dataframe's type list, can verify typeof(mydata). not atomic vector & cause write return error experienced.
