similar to: breaking ties in order() based on many vectors

I'm able to do this as follows, but am wondering if anyone knows a simpler way which still avoids explicit loops? > (mystring <- letters[1:5]) [1] "a" "b" "c" "d" "e" > unlist(sapply(mystring[-length(mystring)], + function(x) paste(x,mystring[(grep(x,mystring)+1):length(mystring)],sep=""))) a1 a2 a3

How can I look up the aspect ratio of a plot, so I can use that to correctly adjust the angle of text which is supposed to be parallel to a line in the plot? The following example code works for a 1:1 aspect ratio, but puts the text at the wrong angle if the plot region is short and wide or tall and narrow. I can't find a par() component containing the plot aspect ratio. It will be for

For example, subtracting 1:2 from the rows of a two-column matrix: > t(apply(matrix(1:6,ncol=2),MARGIN=1,function(y) y - 1:2)) [,1] [,2] [1,] 0 2 [2,] 1 3 [3,] 2 4 > sweep(matrix(1:6,ncol=2),MARGIN=2,1:2,FUN="-") [,1] [,2] [1,] 0 2 [2,] 1 3 [3,] 2 4 Is there a logic to this difference, or is it just a quirk of the history of these

Hi STATISTICA has a function called "Two-way joining" (see http://www.statsoft.com/TEXTBOOK/stcluan.html#twotwo) and the reference material states that this is based on the method as published by Hartigan (found this paper: http://www.jstor.org/pss/2284710 through wikipedia). What is the relationship (if any) between the "heatmap" function in R and this technique? Is there an

Dear R users, I have various vector geometry operations to perform on 3-D coordinate data located on multiple (500+) csv files. The code I have written for the calculations works just fine. I have written a 'for' loop to automate the task of extracting the coordinates from the files and perform the analyses. The loop works reasonable well, but if the number of csv files is greater than

Can someone recommend a more sophisticated way to annotate heatmaps than the ColSideColors argument of heatmap and heatmap.2? In particular, I would like to be able to annotate columns with more than one piece of information, like in Figure 1 of the article at http://www3.interscience.wiley.com/cgi-bin/fulltext/117905619/HTMLSTART / doi:10.1002/hep.22256. Some example data and a heatmap:

In the following, can anyone tell me why length(eee) returns 9? I was expecting 15398, and when I try to add this vector to a data frame with that many rows, it fails complaining that the vector is of length 9. In what I thought was an identical situation with a related dataset, the same code worked as expected. > length(fff) [1] 15398 > str(fff) int [1:15398] 20010102 20010102

We are looking at adding to our storage. We would like ~20TB-30 TB. we have ~ 200 nodes (1100 cores) to feed data to using nfs, and we are looking for high reliability, good performance (up to at least 350 MBytes /second over 10 GigE connection) and large capacity. For the X45xx (aka thumper) capacity and performanance seem to be there (we have 3 now) However, for system upgrades , maintenance

Hello, I am running into this error: /Maximum number of connections from user+IP exceeded (mail_max_userip_connections=10)/ The suggested solution in hundreds of support requests on this mailing list and throughout the internet is to increase the number of maximum userip connections. But this is not curing the problem, it is just postponing it to the moment when the new limit is reached. When i

I have seen posts about this problem, but have had trouble finding how/if it was resolved. I am trying to upgrade from syslinux-3.11 to syslinux-3.86 on RHEL5. On 3.86, when it performs a local boot from hard disk, it just keeps looping back into PXE boot again instead of booting from the hard disk. It will perform a system install just fine, but when it switches to localboot after the install,

Hi, folks. I've got a weird situation here. I'm sure it's something small, but, well, either I've been cursed by a witch doctor, or my eyesight is getting too bad to find small problems. Either way, I'm more than willing to be pummeled for asking such a stupid question, as long as it helps me get it solved. I'm replacing an NT file server with a Samba box (hooray!).

In a previous thread I had problems on openSuse 10.2 building R with optimisation and discovered that if I wanted optimisation I need to turn on -fstore -fsimple1 (the first is to force storage on some Fortran routines , the second is to ensure IEEE arithmetic, with some optimisation). That worked for my desktop. The real problem is to work on our servers (Opterons running SLES9SP3) Make works

Hello, My colleagues and I use lattice for a variety of different purposes, and we came across a couple issues involving legend.R and update.trellis.R: 1. When using xyplot, the shapes in the plots are able to have borders and fill colours, but not so in the legend. I created a short script to isolate the problem (see legend-icons.R and Nofill.png). After some tracing through the source code,

Hi, I am a new user of "R", I am trying to read my data in.. "Cervixhc.dat" used to be in a different directory, now it has been moved to "O:\E&s\APC cervix FINAL (YG,MC,MD)\Manuscript\Data", but when I ran the following program (in red) I got an error message "Error in setwd(dir) : cannot change working directory", and "Error in file(file,

I'm new to Hmisc and trying to get the following to work, but if I un- comment the y-scale list (in order to get a log-scale for the hazard ratio), the error bars become strangely large. The dataframe is simply ODS output from TPHREG in SAS. Can someone point me towards what I'm sure is a naive error? Many thanks! tphreg1_parameterestimates1987$LCL <-

Hi, I would like to report a problem with the levelplot borders in lattice. Description: The borders in levelplots appear when running in a Windows setting, however running the identical command in Linux does not generate the plot with the borders. The commands used were: library(lattice) levelplot(volcano, border = 'black', shrink = c(0.7, 0.7)); The same version of R (2.13.0) and
