@felixcheung @sun-rui (Firstly, sorry I am not pretty much fluent to R).
I am not too sure why it says they are being masked. I anyway added those
here and could pass all tests but still I am wondering why it is and if it is
correct or not. When I change the function name to another, it looks fine but
it looks there are no such functions to mask.
It looks it masks the functions called `read.csv` and `write.csv`. The
console output was below:
```
The following object is masked from âpackage:testthatâ:
describe
The following objects are masked from âpackage:statsâ:
cov, filter, lag, na.omit, predict, sd, var
The following objects are masked from âpackage:utilsâ:
read.csv, write.csv
The following objects are masked from âpackage:baseâ:
colnames, colnames<-, drop, intersect, rank, rbind, sample, subset,
summary, transform
```
Would you please give me some advices on this?
