I have a vector like this: a <- c("thisIsName", "thisIsAlsoName", "andThisName") How to break this into pieces and produce a vector with unique parts: this Is Name Also and This -J

Hi, How to rbind these vectors from a list?: > l <- list(a = c(1, 2), b = c(1, 2, 3)) > l $a [1] 1 2 $b [1] 1 2 3 > do.call(rbind, l) [,1] [,2] [,3] a 1 2 1 b 1 2 3 Warning message: In function (..., deparse.level = 1) : number of columns of result is not a multiple of vector length (arg 1) > -J

I would like to learn AsciiDoc. Is there any good examples how to use AsciiDoc with R? I know that there is packages called ascii to do this, but it would be nice to see some examples how AsciiDoc works with R. Is there an AsciiDoc distribution for Max OS X? -Johannes

I have a string like this st <- "SELECT COUNT(empid), COUNT(mgrid), COUNT(empname), COUNT(salary), FROM Employees" How can I remove the last comma before the FROM statement? -J

Hi, Is there an efficient way recoding variables in a data.frame using base R? My purpose is to create new variables and attach them into old data.frame. The basic idea is shown below, but how to create recoding for A, B and C and assing them into new variables? df <- data.frame(A = c(1:5), B = c(3,6,2,8,10), C = c(0,15,5,9,12)) df$A[df$A <= 3] <- "x" df$A[df$A > 3 &

In conducting studies of animal orientation and displacement, I need to produce circular histograms of angles (bearings in radians 0-2pi) where the centre of the circle indicates very few observations for a given bin of angles and outwardly concentric circles indicate greater frequencies of observations for a given bin of angles. I'd like not to have to write the function myself but I

Hi all, Please consider the following code: require(plotrix) l <- list(rnorm(50),rnorm(50,sd=2),rnorm(50,mean=3)) multhist(l) I have two things I need help with: (1) In the output, there are empty spaces on the x-axis. How would I eliminate these spaces? I want a nice, smooth, empty-spaceless x-axis. (2) How could I add tracing lines to each histogram? I am undoubtedly using the wrong

Hi, R contains many good datasets which would be valuable in other platforms as well. My intention is to use R datasets on SQL Server as a sample tables. Is there a package that would do automatic conversion from the dataset "schema" into a SQL Server CREATE TABLE statement (and INSERT INTO statements)? For example. > str(cars) 'data.frame': 50 obs. of 2 variables: $

Hello useRs and helpRs, Some time ago, in a gallaxy far away (here is the thread : http://finzi.psych.upenn.edu/R/Rhelp02a/archive/46532.html ) we discussed about a graph gallery showing the power of R in that domain. I did some work around that, and there is a (pretty advanced) draft here : http://addictedtor.free.fr/graphiques/displayGallery.php For instance, there are some of my graphs,

Hello everyone, I wanted to know if it was possible to change the color of certain leaves in a hclust object in order to make my graph more readable. I know I can color certain groups but I would like to enter a vector telling the plot function which leaves to color in which color. Thanks in advance, William.

Hello, I'm trying to import a SAS file made using SAS on Unix. Currently I'm using SAS on Windows and I'm trying to import that .ssd04 file to R. The file name of the file is testfile.ssd04 and it is located in 'M:\sasuser'. I'm using Windows XP and R 2.91. Basically what I'm doing is ############ r code ############## > library(foreign) > sashome <-

I intend to draw a plot of y against x. In the background of this graph I wish to creat a histogram of the horizontal variable x. Does any expert know how to produce such a plot? [[alternative HTML version deleted]]

Dear All, I have a question on overlaying a filled.contour (e.g. on soil properties data) and contour (by elevation) in one graph. Both have the same z matrix dimension. I'm able to overlay both graph, but the plots dimension did not overlap well on the same plots. How can I have both filled.contour and contour on the same graph? The commands that I have written are as follows:

Hi, How can I attach chart/plot to a excel file? I would like to create a plot in R eg. plot(1) and save it into a Excel file, eg. test.xls in a same working directory. Regrads, -J

I have timestamps from mysql database: > dput(tstamp) c(1225221868L, 1225221906L, 1225221906L, 1225230997L, 1225231000L, 1225231003L, 1225231152L, 1225231348L, 1225231351L, 1225231400L ) How to convert these into normal dates? Thanks, jrara

Hi, I have dates in this kind of format (day, month, year): > dput(head(dates, 10)) c("6.4.7", "29.12.98", "19.10.91", "20.6.92", "2.9.3", "23.6.3", "13.7.93", "23.3.7", "26.6.95", "15.2.10") So, as you can see, there is no century. How can I change this character data into dates? Any help

Hi, in order to save space for a publication, it would be nice to have a combined scatter and density plot similar to what is shows on http://addictedtor.free.fr/graphiques/RGraphGallery.php?graph=78 I wonder if anybody perhaps has already developed code for this and is willing to share. This is the reproducible code for the histogram version obtained from the site: def.par <-

Hi, there: Suppose I have a couple of data.frames and each one has five columns (one for x-axis, two for y-axis and two for std of y's.) There is another dimensions (besides x and y) which is continuous. My question is, how to plot such series of data frames in one plot (thus, 3-dimensional plot) AND multiple 2-D plots. I am not familar with R's plotting utilities. Thanks. -- Weiwei

Hi R Users, How to use the function polygon() together with the package scatterplot3d? I am trying to color below of the curves defined for the function density().
