similar to: How to override coerion error in 'scan'

I am trying to coerce a data frame column from character to datetime using strptime but keep getting an error because the length of the coerced object is always 9. What am I doing wrong here: ................................................................. > ds <- cbind(1:2, c("02/27/92 23:03:20", "02/27/92 22:29:56")); ds [,1] [,2] [1,]

I need to make plots similar to those produced by the s-plus rayplot function but can't seem to find it in R. These 'vector maps' plot a ray or vector at each specified location. Is there something similar in R ? --Rich Richard Kittler AMD TDG 408-749-4099

Does the 'groups' option on qqmath just color the points differently in the main distribution or does it actually overlay separate quantile plots for each subset? I would like to be able to do the latter. --Rich Richard Kittler AMD TDG 408-749-4099

I am stuck on trying to get the Lattice xyplot to output a separate PNG file each time through my 'for' loop. The files get produced but are empty. Here is the code. I'm running 1.9 on Windows. BTW is there a more efficient way of creating the separate output files than looping over the levels and subsetting? ......................................................... lev <-

Hi all, (if me email goes out as html, than my email client don't do as told, and I apologies already.) We need to downscale climate data and therefore first need to expand the climate from 0.5deg to the higher resolution 10min, before we can add high resolution deviations. We basically need to have the original data at each gridcell replicated into 3x3 gridcells. A simple for loop can do

You probably ought to be using the raster package. See the CRAN Spatial Task View. -- Sent from my phone. Please excuse my brevity.

Hello, I forgot to tell you that I am using Linux OS. And I can?t find directory "src/nmath/standalone". I will send you the test code I am using and the whole operation process.

Is there a way of controlling the font size and alignment of a footnote in an xyplot, or alternatively of using 'mtext' to place a footnote at the bottom of a graph? --Rich Richard Kittler Advanced Micro Devices, Inc. Sunnyvale, CA

Hello, all, I have the same question as the last mail I sent. I have installed libRmath in my system. But I still can not link Rmath through -lRmath. The whole process is as follow.Is there anybody who is so kind to help me find out the problem? I will appreciate very much.

For the appliance of the QCOW2 format, get the UUID of the disk by reading the first 256k bytes with 'qemu-img dd' command. Then pass the read block to the 'file' command.

I believe you need to spend time with an R tutorial or two: a data frame (presumably the "table" data structure you describe) can *not* contain "blanks" -- all columns must be the same length, which means NA's are filled in as needed. Also, 8e^5 * 7e^4 = 5.6e^10, which almost certainly will not fit into any local version of R (maybe it would in some server version --

Hi, I've been trying to get MoH files to sound decent. I've got a hold of Royalty-free Classical music (a safe choice for most of my customers) and I`ve been trying to convert them to the normal telephony/Asterisk format using sox. Unfortunately, it sounds really bad. I don't expect concert hall quality of course, 8000KHz being what it is, but is there a better way to convert

Dear List, I have been trying to extract associations from a matrix whereby individual locations are within a certain distance threshold from one another. I have been able to extract those individuals where there is 'no interaction' (i.e. where these individuals are not within a specified distance threshold from another individual) and give these individuals a unique Group ID containing

Hello, I have the go ahead to fix documentation. For starters I will clean all extraneous crap from the markup. Then fix any errors and typos. If anyone sees any gramatical errors or typos or needed clarifications or expansions or whatever, please post them here. Or additional FAQ entries, etc, all will be considered. I hope to keep most of this conversation on the shorewall-devel list. Any
