similar to: Accessing files on password-protected FTP sites

I am new to R and have been spinning my wheels on the following. *Issue:* I have a membership to a website, and I want to grab data from the website using download.file(). download.file(url, destfile, method, quiet = T, mode = "w", cacheOK = TRUE) The R Documentation is helpful. However, I have been unsuccessful in figuring out how to access the website using my username and

I am very new to R and have been struggling trying to read a basic ".csv" file from a password protected site with the following code: myURL ="http://www.frontierweather.com/degreedays/L15N15PowerRegionAverages_10weeks.txt" test2=read.table(url(myURL),header=TRUE,sep=",") A 'data.frame' is returned into the workspace, however it is not the data contained in

I'm running R 2.11.0 on a 32-bit Windows XP machine. Whenever I try to write a csv file with 'append' set to TRUE, I get this message: attempt to set 'append' ignored. Obviously, this is no good, since R is deleting my previously saved data files, rather than appending to them. What can I do to fix this? -- View this message in context:

Hello everyone, This should be an easy question, I think. I'd like to write a command in a program to set the working directory to whatever directory the file is currently stored in. Suppose I have a file called "myRscript.r", and it's stored in "C:\Rprojects\myRscript.r", and it references other R scripts and data files in the same directory. If I enter the

Hi everyone, I have to fetch about 300 to 500 zipped archives from a remote ftp server. Each of the archive is about 1Mb. I know I can get it done by using download.file() in R, but I am curious that is there a faster way to do this using RCurl. For example, are there some parameters that I can set so that the connection does not need to be rebuilt....etc. A even simpler question is, how can I

What are "good" ways, within R, to download all files (perhaps including folders/directories?) from an FTP site and then save these files to a local hard drive? Is try(getURL) {RCurl} and save() the "best" functions to utilize? Any other suggestions? [[alternative HTML version deleted]]

It's easy to run a linear regression on a simple model without an intercept just by doing this: lm(y ~ x1 + x2 -1) Is there a similar trick to suppress the intercept when your model is in a large dataframe and you don't want to write out the names of individual columns? -- View this message in context:

Is there a quick and easy way to write data frames side-by-side in a csv file with one column separating them? I could just fill them with empty rows so they all have the same height, then cbind them with empty columns in between, but I'm looking for a more elegant solution, if one exists.

I'm trying to upload a file using RCURL:s ftpUpload() to a ftp-server using the following command: > ftpUpload("'VERY.ODD.FILE.NAME(+1)'",to="ftp://x.x.x.x/","' VERY.ODD.FILE.NAME(+1)'",userpwd="USER:PASSWORD") OK 0 The file I'm trying to upload is a very simple text-file but with a bit weird filename. Note the ' on each

Dear all, I have a problem with the command 'getURL' from the RCurl package, which I have been using to obtain a ftp directory list from the MOD16 (ET, DSI) products, and then to download them. (part of the script by Tomislav Hengl, spatial-analyst). Instead of the list of files (from ftp), I am getting the complete html code. Anyone knows why this might happen? This are the steps i

I've been reading some code from an example in a blog post ( http://www.maxdama.com/ here ) and I came across an operator that I hadn't seen before. The author used a <<- operator to update a variable, like so: ecov_xy <<- ecov_xy+decay*(x[t]*y[t]-ecov_xy) At first I thought it was a mistake and tried replacing it with the usual <- assignment operator, but I didn't

Hi, I have problems downloading complete folders via ftp with R. Single files work fine. I tried Rcurl, but it does not work. This is my code: url = "ftp://disc2.nascom.nasa.gov/data/TRMM/Gridded/Derived_Products/3B42_V6/Daily/2009/" filenames = getURL(url, ftp.use.epsv = FALSE, ftplistonly = TRUE, crlf = TRUE) filenames = paste(url, strsplit(filenames, "\r*\n")[[1]], sep =

R-helpers: I'd like to be able to store all the file information from an ftp site (e.g. file and foldernames) through an R command. Any ideas how to do this?

Dear list members, I encountered this problem and the solution pointed out in a previous thread did not work for me. (e.g. install.packages("RCurl", repos = "http://www.omegahat.org/R") I work with Ubuntu Hardy, and installed R 2.6.2 via apt-get. I really need RCurl in order to use biomaRt ... any help would be greatly appreciated. Best wishes, Emmanuel

Hi Patrick, Greetings from !(sunny) Pittsburgh. What's the scoop on RCurl on windows (XP)? I've tried to install RCurl_0.92-0.zip and RCurl_0.9-3.zip, with both R 2.7.2 and R 2.8.0 from the RGUI (utils:::menuInstallLocal), and get the error "Windows binary packages in zipfiles are not supported". which (according to google's one and only hit) comes from a perl script.

Martin, Well, thanks for jumping in! We need all the help we can get ;) I changed the execute bit as you suggested and recompiled, no luck, still the same error message. Below is the output you wanted me to look at, its a bit beyond me so I include both a brief grep summary and then the whole enchilada. I do note that my output is different from yours, but I'm not sure how to interpret. I
