similar to: import text file into R

I tried to read a CSV file in R. The file has about 100,000 records and 75 columns. When used read.delim, I got this error. I am using R ver 10.1. > los<-read.delim("file.csv",header=T,sep=",") Warning message: In scan(file, what, nmax, sep, dec, quote, skip, nlines, na.strings, : Reached total allocation of 1535Mb: see help(memory.size) Thanks -- View this message

Using read.table now on large files. Scan should be faster reading and parsing the files if a 'what' list is provided. How would I generate a what list that repeats the the last 4 elements n (n=14 or 10 or 8) times? whatlist=list(Tstamp="",Condition=0,A1=0,B1=0,C1=0,D1=0) All are numeric, either decimal or hexadecimal. Thanks in advance, Alex van der Spek

Hi, I'd like to import a 154x1 vector of a stock monthly returns from a text (or excel spreadsheet) into R. I need to work on this vector by calculating mean, variance and use it for more complex operations. What is the best function to do so?

On both postscript() and x11() devices, the regular text is heavier than the expression text.

Dear all, I have -hopefully- a tiny problem.

My first na?ve approach was to scan the text file in order to get a vector v. Then I did: class(v) <- "dist" attr(v, "Size") <- 4 But, of course,
