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 would like to use R to process a list of text strings. The text strings are filenames, encoding experimental settings. Based on the information in there I'd like to select certain files and copy only the selected files to another directory. The files are images and there is no need, actually no desire, to open them. Is there a way to use R for copying and pasting files with any

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

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'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:

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

Hi, I have two vectors, mag and i, and I want to generate a of vector where each element is the frequency of mag which is greater than i. i produced the following code. However I get the following error: mag<-rnorm(40,5,3) i<-seq(floor(min(mag)),max(mag), 0.5) freq<-sum(mag>=i) Warning message: In mag >= i : longer object length is not a multiple of shorter object length

Hi there: I am new to R and creating a boxplot panel chart to show a test result. I have four output variables (OV1, OV2, OV3, OV4) reflecting effects of the variation of three status parameters (SP1, SP2, SP3) on them at three different locations (Loc1, Loc2, Loc3). My plan is that displaying ONE OV change with ONE SP over three Loc in each boxplot (i.e., Loc is X axis and OV value is Y axis).

this is from my extensions.conf, the first three patterns are for toll-free numbers, and fourth pattern is for other numbers, where an AGI is called for authentication. now when I dial 011448000664327 if falls into the fourth pattern, where as it should be matched by the first pattern. Any suggestions 1 - exten => _01144800XXXXXXX,1,Dial(${MAG}/${EXTEN:3},45,tT) 2 - exten =>

Full_Name: Allyson Williams Version: 2.1.1 OS: Windows XP Submission from: (NULL) (203.25.1.208) I'm using the 'Circular' package to plot windroses. I think the output table (see out2$table below) is incorrect when using different rotations. More precisely, when a rotation is used for the plot, the output table stuffs up. This example is from the code in the help notes, although the

Hi everybody, I have trouble installing my own package under R 2.1.0 (it is fine under R 2.0.1). My OS is Windows NT. I installed my package 'mag' by using menu "Packages/Install package from local zip files....". It's fine (html package description was updated). But when I typed in library(mag) it gave me error: Error in library(mag) : there is no package called
