Hello, in the data.frame "resultsfuzzy" I would like to replace the characters in the second column ("5a", "5b", ... "5e") with numbers from 1 to 5. The data.frame has 39150 entries. I seems to work on samples that are << nrow(resultsfuzzy) but it takes suspicously long. Do you have any suggestions how to make the character replacing more

Hello, I would like to remove the last 8 digists of character strings in a vector. Below I added a couple of elements from that vector. I have a problem defining a pattern to replace the digits using for example "sub". Removing the ".tif" part works fine using sub('.tif',"",x), but how do I get rid of the four preceding digits? Thanks for your help, Kim

Hello, I have a time series of data as a data.frame. Occasionally there is one or more days missing (e.g. data available for days 2, 3, 4, 8, 9, 10 --> missing days between 4 and 8). The experimental time information can be found in the 2nd column of "data". I would like to have a continuous time line with one time point per day. Therefore I try to insert lines for the missing

Hi, I'd like to construct a somewhat unusual barplot. In "barplot" I use beside=F as I'd like to have stacked bars. The height of each bar is always the same. Information in my plot is coded in the color of the bar. I therefore need to be able so assign a different combination (or order) of colors to each individual stacked bar. In the example below, the combination of

Hello, in a three dimensional coordinate system, I'd like to find all my experimental data points that fall within an ellipsoid around a fixed coordinate. The fixed point is defined by (x.coord.point, y.coord.point, z.coord.point). The coordinates of the ellipsoid are given by the three vectors x,y,z. In a previous version of my code, I simply used a box instead of an ellipsoid to sort

Hello, I very much enjoy rgl! But when converting the screen output to pdf using rgl.postscript I have encountered three problems: (1) I don't seem to have control over font sizes and point sizes (of added points) in the pdf output. I tried cex from "plot" but that does not have an effect. Initially I got some plots where fonts and especially points were far too small. But now

Dear help-list, I would like to perform a linear regression on the log10 of the two vectors ov.mag.min and res.600nm. The slope and intercept of the regression I use to plot a wider range of ov.mag.min in a double log plot. For a linear regression on only tow points, wouldn't I expect the results for two.points.min to match pretty exactly res.600nm? It does not seem to be the case here.

Hello, I'd like to reproduce the standard biplot with pc.biplot=TRUE using xyplot in lattice in order to assign different symbols to groupings of observations (similar to the example in fig. 11.2 on page 285 in DAAG). In order to reproduce the biplots I need to know how to scale the observations and variables. In ?biplot.princomp I found that the variables are scaled by 'lambda ^

Hello, I am trying to run some AMOVA analyses with the amova function in the package ade4. When running the example dataset provided in ade4, I noticed a difference between the published results from the same data (Excoffier et al. 1992) and what ade4 calculates. Below are the data for "within sample/population" from ade4 and from the haplotypic distance matrix in the paper:

Hi, with the code below I try to organize sections of a data.frame. The dataframe has 9 data columns. I'd like to order the columns of the data.frame by the sum of the columns' entries. The sections of the columns are identified by "i". The order of the columns is given by the vector "z". Each section of the data.frame is ordered differently. This can be seen when

Dear R-users, I would like to create pdf files with varying paper sizes. The paper size is determine by the number of plots that I squeeze on a page using par(mfcol). I also add text to each of these plots. I observed that depending on the number of plots per page, the default character size is changing, leading to differing font sizes in my plot annotations. I would like to use cex to

Hello. Nice to meet you. My name is Seung Jae Lee, a graduate student in UIUC CEE, who is working in NCSA for the present. Nowadays I am trying to develop LLVM backend to spit out CHiMPS assembly code. In the process, I installed LLVM codes on my home directory in the host computer. But I don't think it was installed properly. While bootstrapping the LLVM C/C++ Front-End, I met several

Hi, I'm running asterisk 1.4.22 on a debian server. I have php5 installed and it works correctly command line. When trying to run a php script via AGI, I get messages such as: GI Tx >> I> AGI Rx << #!/usr/bin/php5 -q AGI Tx >> 510 Invalid or unknown command The scripts are completely executable and owned by asterisk -rwxr-xr-x 1 asterisk asterisk Googling is not helping

Hi! I am currently working on setting up an Asterisk system, and I was wondering if anyone has worked on an alternate mp3 player to mpg123. We have a library of MP3 files that we would like people to be able to select and play over the phone -- and this will require pause & resume, as well as fast forward / reverse (jump forward / jump back). It doesn't seem like mpg123 can do this. Is

Dear List, I need to print out each of 'k' levels of a factor 'n' times each, where 'n' is the number of elements belonging to each factor. I know that this can normally be done using the gl() command, but in my case, each level 'k' has an unequal number of elements. Example with code is as below: vc<-read.table("P:\\Transit\\CORRECT

We've been running an Asterisk-based phone system here in our office for a year and a half, and it's pretty much been running smoothly. One employee who works out of the office has a problem that she can't make outgoing calls on a temporary basis every so often (a few times a day). No one else has this problem, her settings are fine, and she regains the capability spontaneously with no

Hi, For a few weeks now, our asterisk server has been experiencing something very odd. From time to time, voicemail.conf would go blank. We finally tracked it down to happening when someone attempts to change their password. It seems the file is touched, but not written to, and we're left with a blank voicemail file. Permissions seem to be fine: -rw-rw-r-- 1 asterisk asterisk 12707
