Can you show us the first line of the file?

The error means that in one of the values you specified as numeric (first, second, third, fourth, fifth, seventh, eighth, ninth), it found the character value it displayed.

Otherwise, this looks like a good use of scan.

I am trying to read a large (500000+ lines) with scan() as read.table is unable to read it.

I get a strange error (below) which says that 'a real' was expected and '5' was read. Can someone help?

> tmp2 <- scan(file="tmp2.txt", what=type, sep=",", quote="\"",
dec=".", skip=1, nmax=541502)
