[Rd] read.csv

[Dirk Eddelbuettel]

As an aside, the odd format does not seem to bother data.table::fread() which
also happens to be my personally preferred workhorse for these tasks:

> fname <- "/tmp/r/filename.csv"
> read.csv(fname)
   Gene             SNP prot log10p
1 YWHAE 13:62129097_C_T 1433   7.35
2 YWHAE 4:72617557_T_TA 1433   7.73
> data.table::fread(fname)
     Gene             SNP   prot log10p
   <char>          <char> <char>  <num>
1:  YWHAE 13:62129097_C_T  1433E   7.35
2:  YWHAE 4:72617557_T_TA  1433E   7.73
> readr::read_csv(fname)
Rows: 2 Columns: 4
── Column specification ──────────────────────────────────────────────────────────────────────────────
Delimiter: ","
chr (2): Gene, SNP
dbl (2): prot, log10p

ℹ Use `spec()` to retrieve the full column specification for this data.
ℹ Specify the column types or set `show_col_types = FALSE` to quiet this message.
# A tibble: 2 × 4
  Gene  SNP              prot log10p
  <chr> <chr>           <dbl>  <dbl>
1 YWHAE 13:62129097_C_T  1433   7.35

That's on Linux, everything current but dev version of data.table.
