Re: readAsciiTable memory problem

Dear Yongfei,

Under the hood, readAsciiTable is reading the table and then writing a temporary file
to a directory like /tmp without the header information, and then reading this temporary
file back in. It does remove this temporary file before leaving the function.
It's also generating some string arrays, which can be expensive if you are doing this a lot.

If you can send me some examples of your ASCII files, there might be another
way to read them without using readAsciiTable, and hence avoiding the writing
of that temporary file.

By they way, how many is "a bunch"? :-)
