How View function looks like, I did not find it in base and other packages I use.

No documentation for ‘Viev’ in specified packages and libraries:
you could try ‘??Viev’

Neither I. Your message is rather cryptic. You can get number of columns by

ncol(x)

NameData[,1] does not have anything to do with number of columns, it gives you first column of NameData object (if NameData object is data frame or matrix).

The error seems to me pretty straightforward. First line of mirnat.txt is a header and based on separator (read.table assumes it is white space) read.table expects 62 elements in any row.

Maybe it is problem in column names (they may contain white space as a part of a name - like e.g. in "New York").

Or you wanted to use first column as row names but this column has a name, so there is one name more for columns.

BTW, you may have broken keyboard, there are no capital letters and EOLs in your mail.

Cheers
