Dear all, I have a string (a file path in windows system) contains several "\"s. When I copy and paste it into R for assignment to an variable, the "\"s are always interpreted as escaping characters. How can I keep...

Dear all, How can I get the duplicated elements from a vector? For example, x <- c("yes", "no", "yes", "yes", "no", "not sure"), how can I filter out all the elements which occured >=2 times? Thanks for any help! Regards...

Thank you, Professor Ripley. It is exactly what I need. Best wishes! Leon Prof Brian Ripley wrote: > By reading from a file or connection, as in > > foo <- scan("", "", n=1) > c:\tmp\foo > > The parser always interprets \ in strings, so...

Hi, friends Is there any functions for object comparing? For example, I have two list objects, and I want to know whether they are the same. Since the the components of list are not necessary atomic, this kind of comparison...

Dear all, Which data structure in R can mimic hash in PERL? I'd like to set up a lookup table, which could be accomplished by HASH if using PERL. Which of the data structures in R is the most...

Dear R users, For a uni-variable distribution represented in a numerical vector, we can obtain a distribution function using 'ecdf', and then calculate corresponding p-values. But if I have a 2-column dataframe representing a bi-variable joint...

Dear R users, I am trying to customize the .Library.site in the file etc/Rprofile.site under Windows XP, but it seems that the setting doesn't take effect. My setting is: .Library.site <- "d:/site-library" But after...

Dear all, I have a question about "union". "union" handles two vectors' elements to get their union, but I have many vectors and I want to get the union of all of them. So I wrote a loop: all <-c...

Hi, all I have a question of adjusting the output of a data frame with many columns. By default, print() will print out several columns according to the window size, and then it scrolls down and print out left columns...

Oh, sorry, my own fault. I had set a HOME evironmental variable, and there was a .Rprofile in it, and the setting of .Library.site was overriden there. Regards, Leon Leon Yee wrote: > Dear R users, > > I am trying to...
