When read.table imports a table that includes a header called 'Date', it tries to recognize the date format. For example, if one imports this data from Yahoo finance, the Date column is automatically transformed to Y-m-d, whereis in the data it appears as m/d/Y: myData <-

Hello Group, I'm trying to learn R and am having a problem getting output from a function I'm trying to write. The problem is clearly one of scope, but I can't find the documentation that tells me how to get around the issue. Here is an example of my problem. testfunc<-function(x) { y<-10 print(y) print(x) } testfunc(4) The variables x and y are accessible during execution

I'd like to use a string to refer to an R object with the end objective of going through a loop and saving various files of the same name with different contents using a numbered suffix. # This will be the loop counter and file suffix. master.i <- 1 # This is the generic file name. unislopes <- c(1,2,3) # This assigns the data to the correct file name "unislopes1".

Hi R users, I have a problem in downloading Yahoo Finance data from R. I have tried an example given in R, to download.

Hi all, I just had a rather unpleasant experience. After considerable work I finally got a script working and set it to run. It had some memory allocation problems when I came back so I used Windows to stop it. During that process it told me that the script had been changed and asked if I wanted to save it. Not being positive that I'd saved the very last changes I said yes. Now when I

Hello, Beginner, sorry if this is wasting anyone's time, but have been working on this for a couple of days now, think it should have take a few hours!

Hi, I've been performing some TukeyHSD tests in R and have come across papers that include all the necessary information (means, sample size and SE) for me to perform the piecewise comparison by hand. I can reach out to the authors to get the original dataset, but it raises the question, can I perform the Test with the information I have and save myself some time? Is there a way to somehow

Hi there, I am trying to run an MCMC on stable isotope data from certain organisms to determine their dietary habits in the package SIAR. I have prepared my data according to Inger, R., Jackson, A., Parnell, A., Bearhop, S. : SIAR V4 (Stable Isotope Analysis in R) an Ecologist's Guide (also better known as 'SIAR for dummies'), which is as follows: - consumer data table (columns

I'm absolutely not brilliant with R yet and working with package SIAR. 1) SIAR reads the first column of a table.txt as "int" instead of "num". Who can help? 2) I therefore made tables with a data.frame() > that seems to work. But at the end of the loading proces of the SIARmodel, I get a warning screen with "Session Aborted". Everything crashes and I can start

Hello, In regards to one of the 'current issues and debugging' - Why does my transfer die with something like the following error? I found that this error occurs also if the path log file = /xyz/abc/rsyncd.log in your rsyncd.conf points to a folder that doesn't exist. Hope this helps!

Dear List, I'm getting the error: object of type 'closure' is not subsettable And am not sure how to get around the problem. I've included two short code sets below. One that shows what I want to do and works, but without using the function much, and another that tries to use the function but causes the error. # THIS WORKS AND SHOWS WHAT I'D LIKE TO DO a <- c(1,2,3) b

Sorry about not being specific enough. I will try and be more so in the future. Here is what I have currently: Apple X-serve running Yellowdog (a Redhat 9 port for ppc) with 1GB of RAM, 3 60GB HD not setup as RAID. They are individual partitions (/var and /, /home and /shared). The shared partition is strictly for Samba file sharing. I build in a matching user in both the system and in

Hi, I'm trying to download some data from the web and am running into problems with 'embedded null' characters. These seem to indicate to R that it should stop processing the page so I'd like to remove them. I've been looking around and can't seem to identify exactly what the character is and consequently how to remove it. # THE CODE WORKS ON THIS PAGE library(RCurl)
