Dear R-users, I have encountered the following problem every now and then. But I was dealing with a very small dataset before, so it wasn't a problem (I just edited the dataset in Openoffice speadsheet). This time I have to deal with many large datasets containing commuting flow data. I appreciate if anyone could give me a hint or clue to get out of this problem. I have a .dat file

Hola. Con r <- scan(txt, character(0)) creo que debiera montarse el texto carácter a carácter. He comprobado que funciona pero no he validado la importación del texto.

Hi, I am looking for an efficient way of skipping big chunks of lines on a connection (not necessarily at the beginning of the file). One way is to use read lines, e.g. readLines(1e6), but a) this incurs the overhead of construction of the return char vector and b) has a (fairly remote) potential to blow up the memory. Another way would be to use scan(), e.g. scan(con, skip=1e6, nmax=0)

Hello, I have a problem to read a csv table.

Hola a todos, Me gustaria leer el texto que se encuentra en http://dl.dropboxusercontent.com/u/9601860/txt.txt He intentado txt <- 'http://dl.dropboxusercontent.com/u/9601860/txt.txt' r <- scan(txt) #Error in scan(file, what, nmax, sep, dec, quote, skip, nlines, na.strings, : # invalid multibyte string at '<ff><fe>M' r <- read.table(txt, header = FALSE)

It seems to me the following should work (in fact, it comes from someone's SPlus file). Instead, it reads the first 8 lines and then spits out syntax errors. Using nlines=36 works. Using nmax does not. Intel RH5.2 with R90.0. Debugging shows it must be internal. Jim junk <- scan(file="",list(i=0,r1=0,r2=0,lull="",day=""),n=5*36) 1 3 5 no 1 2 1

No matter how I´ve tried o find a solution for this simple question, I can´t. Sorry for bothering with such a matter. I have an excel-files with some empty cells=missing values.
