Working through the R archives and webspace, I've mostly proved to myself that I don't know enough about what statisticians call "Curve Fitting" to even begin translating the basics. I'm a sysadmin, and have collected a variety...

I've observed something I don't understand, and I was hoping someone could point me to the right section of docs. There's a portion in one of my analyses in which I am wont to sort a data...

Thank you Jim and David for your help. The 'levels' call is not a misdirection, in my actual dataset it is necessary because the flows aren't symmetrical. So while your solution is quite elegant David, it doesn't apply...

Hi All, I have a data set of daily measurements of river flow. I would like to create a "ts" object from this data. Here's a sample data set: date <- as.Date(c(1:300), format="%Y") year=as...

Dear List, I would like to plot the diagnostic plots for an anova object and the anova table in a single window divided into 5 plotting regions. Plotting the diagnostics is simple engough but is there an easy way to...

Greetings, all. I'm fiddling with some text manipulation in R, and I've found something which feels counterintuitive to my PERL-trained senses; I'm hoping that I can glean new R intuition about the situation. Here's an...

hi are you using a 64bit system? 32 bit systems can only allocate about 3GB to a single process. http://msdn.microsoft.com/en-gb/library/aa366778.aspx I used to use 32bit winXP, then moved to 64bit Ubuntu8.04...

Greetings. At the moment, I'm applying R to some AIX 'nmon' output, trying to get a handle on some disk performance metrics. In case anyone's interested: http://docs.osg.ufl.edu/tsm/pdf/ some of them are more...

Hi I'm using Ubuntu 7.10 with 2GB RAM and a 2GB partition of the HDD set aside as a swap drive. I'm trying to write programs which are quite RAM intensive and as such I sometimes run...

Our configuration: R 2.6.1, DBI_0.2-4, ROracle_0.5-9, all running on a dual-processor 64-bit Ubuntu 6.06 system. If you run the following drv <- Oracle() conn <- dbConnect(drv, '<oracle user>/<password>') sql...

I feel dirty. I have some graphs I'm building to communicate chargeback rates and service usage for our backup system here at the University of Florida. These come down to daily data points on a graph of number-of...

Is there somewhere a succinct guide to just how much extra crud we need to install on RHEL to make use of EPEL packages? [root at troll-1 noarch]# rpm -ivh R2spec-4.1.0-1.el6.noarch.rpm error...

Hello Baptiste and others, I tried your example with my dataset, and for a few days I thought it worked for me. But I realized yesterday that the result wasn't quite what I hoped for. In my actual data...

Hi I came across this strange bug the other day, I'm not sure how to solve it and I wonder if anyone can even replicate it. Using OS Ubuntu 7.10 Step 1) Make an R package using the...

I have recently been introduced to R for win95 and have been impressed by it. It seems to outperform S-Plus greatly. I have had 2 problems. I am using visual basic to automate an analysis. The vis basic routine...

Dear All I'm logging the stdout and stderr of an R program into two separate files (stderr.txt and stdout.txt) using sink() I would like to append extra information such as "date", "memory usage" etc to every line...

I understand that in order to get the sum function to ignore missing values I need to supply the argument na.rm=TRUE. However, when summing numeric values in which ALL components are "NA" ... the result is 0.0 ... instead...

I am trying to use POSIX datetime objects rather than chron datetime objects but am having difficulty with POSIX in a time series. My question: Once a POSIXct vector is bound to a time series, is there a function to...

I recently called plot(x,y) where x was an array of POSIXct timestamps, and was pleasantly surprised that it produced a nice plot right out of the box: z <- as.POSIXct(c("2006-10-26 08:00:00 EDT...
