Hi all, any guy who knows how to print a data frame without column names printed? I didn't find a parameter in print() function to turn off this. Neither in options(). Thanks in advance.

hi all If I wanna get the total number of lines in a big file without reading the file's content into R as matrix or data frame, any methods or functions? thanks in advance. Regards

Hi all, for example: > X<- rnorm(1000) > X0 <- 0.899 I want to draw a density distribution plot with a arrow pointer indicating the position of X0, meanwhile, giving out the p-value. any functions? Thanks very much.

Hi all I want to draw a graph containing points and edges. Package graphics could do this. However I want to make each those points and edges clickable with a hyperlink on them. Anybody know how to do this? Thanks...

for example, >x <- read.table(....); here x is a vector containing my data to be analyzed. >hist(x,plot=TRUE,breaks=200) then I got a histogram graph. However, How can't get a smooth curve based on the histogram...

Hi dear Rers, I am using SSOAP package to access SOAP service at NCBI. I followed the example code in SSOAP but failed. > z <- .SOAP("http://www.ncbi.nlm.nih.gov/entrez/eutils/soap/soap_adapter.cgi", method="run_eInfo...

Hi, I got a amd 64 + debian/pure64 system. R is installed by apt-get so it's no doubt that R is for 64bit. My question is, for those packages, for example, ipred, it's difficult to find in...

Hi all. I used to use write.table() to write data into file. However , it seems that write.table() waste a lot of memory on caching temporary variables. Thus it ofen fails on writting larg matrix/frame into file. I...

hi R folks, I need read a file from hardisk or www web. Then I need to define some new functions according to the contents of the read file. For example, i need write a package name "mypackage" like this...

I got a dirty way to solve this. write a temp .R source file including these new functions, then >source(this_temp_file) but I don't know if there are some temp directory for R to store temp files...

Hi all Two computers: one is my desktop PC, windows2000, R 1.9.1. Physical RAM 256MB, Swap (Virtual memory) 384Mb. When I allocate a large matrix, it firstly uses up RAM, then use swap space. In windows' task manager...

Thanks. A small arrow may be more nice-looking than a long cutting line. and, another question, how to get the p-value of the position of X0? If the whole distribution is not as regular as norm, chi-square...

Sorry for my confusing expression. I need create some new temp functions after the package is loaded. And these new functions should be visible and usable. Functions could be returned as a object, as Liaw mentioned. However I can't...

haha.... debian vs rpm again... everywhere.. On Tue, 14 Dec 2004 10:30:07 +0100, Siegfried Gonzi <siegfried.gonzi at stud.uni-graz.at> wrote: > doktora v wrote: > > >I'm using SUSE with success on intel laptop and AMD desktop...
