Again me. I want to plot the numbers on the bars of a barplot. This can be done using hist function when setting the label argument true (i.e. data <- c(1,2,3,4) hist(data, labels=T) When I try this using barplot I get an error: > barplot(summary(data), labels=T) Error in axis(if (horiz) 2 else 1, at = at.l, labels = names.arg, lty = axis.lty, : formal

Hi, I have a few hundreds files with numerical information of different length but with the same column structure. I use the following code to get summary statistics fplist <- list.files(pattern=".*analysis") for (fp in fplist){ x2 <- read.delim(fp) summary(x2) } Summary gives something like: summary (x2) V1 V2

Sorry for the question, but I really cannot find the right search terms to find an answer.. I have a data frame with strings in some of the columns. I want to know all the rows where the strings in both columns are equal. How do I do this? Thanks, Bernd [[alternative HTML version deleted]]

Hi there, I want to run an R script on a cluster with qsub. Obviously I don't want to display any X window, but I want use png() or something else to write out images. Unfortunately I get the following error message: > png(filename = " ALL.png", width = 480, height = 480, pointsize = 12, bg = "white", res = NA) Error in X11(paste("png::", filename,

Hi there, I am looking for R-packages that can help me visualize properties on nucleotide sequences. I want to display sequences in the 1-100K base range as lines and plot features above and below those lines. Any ideas would be welcome. Thanks, Bernd

Hello, I would like to read sets of files within a folder, perhaps using recursive methods. Right now, I rename the files before import. It would be even better to do this without renaming files, without providing explicit filenames, perhaps by importing files based on chronology, and translating each filename into a header? Please excuse my ignorance, and help cure my clunky programming

Dear all, I am new in R so please forgive the "dumb" question... I am used to work with Mathematica where it is possible to display a 2D array as a collection of shaded squares. The gray level there represents the value of the array element. It is basically a projection of a 2-dimensional histogram. After a lot of reading I still haven't found that kind of function. I would be

Dear all I have a problem with assigning my own labels to the axis of a plot. I want to substitute the given labels e.g. 1,2,3,... with a vector of values and strings e.g. "12.23", "1.34", "245,5", "Result". B.t.w. how do I rotate these labels so they don't overlap???? I want to use the image function to plot. Thanks for your kind help. Bernd

Hi there, I have something that appears to be a factor called drug: Typeof(drug) => Integer As.numeric(drug) gives a long list Levels(drug) gives a long list, too. Now I want something like the summary function does: I want to count how often each level occurs in the given vector. My problem is that summary gives me a list with counts that is incomplete and adds the

Hi, I would like start R in BATCH mode and submit my own parameters. Or in other words, I would like to specify variables from the command line and execute a script using those. I have been looking at commandArgs and calling R from the command line under bash: R CMD BATCH --no-save --args -filename="$filname" -- r-test.R r-test.Rout The problem here is, if $filename contains

Dear Gerrit Thanks a lot. "rbind" seems to be the right function. Unfortunately there is a shift in the x-axis (see pdf). There are 52 trapcatch values each, m and w, but m$trapcatch and w$trapcatch are shifted up to x-value 60. The follow-up lines for temp and humidity are fine. Thanks Sibylle setwd("~/Desktop/DatenLogger2017") # am Mac sks trap =

Hello, I used read.xlsx to read in Excel files but for large files it turned out to be not very efficient. For that reason I use a programme which writes each sheet in an Excel file into tab-delim txt files. After that I tried using read.table and read.delim to read in those txt files. Unfortunately, the results are not as expected. To show you what I mean I created a tiny Excel sheet with some

Dear list, has anyone written a package/function in R for computing a point- biserial resp. biserial correlation? Thanks in advance Bernd

Hi, Someone recently told me that R is not working well with other programs in a clustered environment. I believe we are using gensoft and working in a redhat environment. What was also mentioned was that there are problems when running multiple R instance at the same time. Personally I haven't experienced any of the described difficulties but would like to get your feedback and potentially

Dear Rs: Hi, I am trying to read a big text file (nrows=243440, ncols=144). It seems the computational time of all the read methods (scan,readtable,read.delim) is not linear to the number of rows I want to read in: things became really slow once I tried to read in 100000 lines compare to 10000 lines). If I am reading the profiling result right, I guess scan wouldn't help either. My

Hi, It would be great if someone would add write.delim() as an adjunct to write.table(), just as with write.csv(). I store a lot of data in tab-delimited files and can read it in easily with: read.delim("text.txt", as.is=TRUE) and would love to be able to write it out as easily when I create these files. The obvious setting needed for write.delim() is sep = "\t", but in

I have a very large tab-delimited file, too big to store in memory via readLines() or read.delim(). Turns out I only need a few hundred of those lines to be read in. If it were not so large, I could read the entire file in and "grep" the lines I need. For such a large file; many calls to read.delim() with incrementing "skip" and "nrows" parameters, followed by grep()

Dear ExpeRts,t I am trying to read tab delimted data produced by somewhat brain dead software that seems to think it's a good idea to have an extra tab character after the last column - except for the header line. As explained in the help page, read.delim now assumes that the first column contains the row.names (which is not even wrong) but now and all col.names get shiftet by one column.

hi: I have matrix with dimensions(200 X 20,000). I have another file, a tab-delim file where first column variables are row names and second column variables are column names. For instance: > tmat Apple Orange Mango Grape Star A 0 0 0 0 0 O 0 0 0 0 0 M 0 0 0 0 0 G 0 0 0 0 0 S 0 0 0 0 0

Hi jpm miao, You can get CSV files that can be imported into Excel like this: library(prettyR) sink("excel_table1.csv") delim.table(table(df[,c("y","z")])) sink() sink("excel_table2.csv") delim.table(as.data.frame(table(df[,c("y","z")])),label="") sink() sink("excel_table3.csv")
