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, 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 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 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, 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 ^

Hi, I'm working on a data set that contains a couple of factors and a number of dependent variables. From all of these dependent variables I would like to calculate mean, standard deviation and quantiles. With the function FUN I get all the means and stdev that I want but quantiles are only calculated for the first of the dependent variables (column 8 in the summarize command). What do I

Hello, I've got a matrix consisting of one column with n rows. Each field in the matrix is filled with a character vector. I would like to convert this matrix into a character vector containing the B03_MAH-type entries from the beginning of each row and a data.frame that contains the numeric data, but I am stuck. I have tried to use textConnection with sep = " " but since

I was trying to build the Linux kernel with clang and observed a crash due to incorrect loop optimization: drivers/base/firmware_class.c extern struct builtin_fw __start_builtin_fw[]; extern struct builtin_fw __end_builtin_fw[]; static bool fw_get_builtin_firmware(struct firmware *fw, const char *name) { struct builtin_fw *b_fw; for (b_fw = __start_builtin_fw; b_fw != __end_builtin_fw;

I am trying to do a Nonparametric Tukey-type multiple comparison post-hoc test to determine which groups are significantly different. I have read the dialogue on this topic from the R-help, and am still not clear why no statistical packages include this test as an option? Is it not an appropriate test to conduct on non-normally distributed data? Is the only option to calculate it by hand

I wanted to know if most of the packages that are available on windows , would they be available on Ubuntu/Linux? If not can I compile the source code of those package ? Has any one of you used the packages on Ubuntu ?
