Hi, I use the functions socketConnections() and getConnection() which are working fine. Thanks to the authors. After opening nicely some socketConnection, getConnection(3) returns something like : description class mode text opened can read can write "->127.0.0.1:7496" "socket" "wb" "binary" "opened" "yes"

I'm finding that readLines() and read.fwf() take nearly two hours to work through a 3.5 GB file, even when reading in large (100 MB) chunks. The unix command wc by contrast processes the same file in three minutes. Is there a faster way to read files in R? Thanks!

Hi Jim I am trying to prepare a bed file to load as accustom track on the UCSC genome browser. I have a data frame that looks like the one below. > x V1 V2 V3 1 chr1 11255 55 2 chr1 11320 29 3 chr1 11400 45 4 chr2 21680 35 5 chr2 21750 84 6 chr2 21820 29 7 chr2 31890 46 8 chr3 32100 29 9 chr3 52380 29 10 chr3 66450 46 I would like to insert the following 4 lines at the beginning:

Dear R users and Helpers I am beginner with using R and interested in carrying out certain task for my statistical research. I am reading data for a text file, which could contain data in following pattern x y 8 10 11 14 16 16 18 15 6 20 4 4 20 18 As per the example I have two columns and 7 rows of data in each. However is real life data situation I may not know how many columns are present

Does something like this get you close: x <- list() keys <- LETTERS[1:6] # create for (i in keys){ x[[i]] <- data.frame(a=1:5, b=1:5, c=1:5) } # output output <- file('tempxx.txt', 'w') for (i in keys){ write.table(i, row.names=FALSE, col.names=FALSE, file=output, quote=FALSE) write.table(x[[i]], file=output, quote=FALSE) } close(output) On Wed, Jul 2,

Hi All, I have some data I need to write as a file from R to use in a different program. My data comes as a numeric matrix of n rows and 2 colums, I need to transform each row as a two rows 1 col output, and separate the output of each row with a blanck line. Foe instance I need to go from this: V2 V3 27 2032567 19 28 2035482 19 126 2472826 19 132 2473320 19 136 2035480 135

Dear all, I have produced a barplot and wish to alter the axes a little. In place of the variable names appearing on the x-axis, I'd like to have the numbers 1986 to 1995. I have tried using the argument xlim=c(1986,1995) in the barplot command but receive: "Error in plot.window(xlim, ylim, log = log, ...) : invalid 'xlim' value" Also, on the y-axis, the values are

Hi, I have my data in below format. position var1 var2 2 .1 10 3 .29 89 12 .56 100 425 .34 1234 6546 .12 21 .... ..... ..... .... ..... ......

Dear all, I've been trying to superscript the '2' in the following command (I don't want the '^' displayed), but as yet haven't had much luck. I've tried both the paste and expression commands, but neither have brought me any joy! mtext(side=2, line=5.5, "Monthly Precipitation (mm x 10^2/month)", font=2, cex=1.1) Any advice would be much appreciated,

Dear R useRs, is there any simple, build in function to match specific regular expression in data file and write it to a vector. I have the following text file: *NEW RECORD *ID-001 *AB-text *NEW RECORD *ID-002 *AB-text etc. Now I have to match all ID fields and print them to a vector: 001 002 etc. I know that this is very simple with Perl or R-Perl interface, but if possible, I want to do

Hi! I'm completely confusing myself attempting to solve this one. Is there a simple way of removing particular ASCII characters from a CSV file using R. Hopefully something simpler and faster than cycling through each individual character and comparing them to a list of characters to remove then deleting as necessary. As always, any help would be appreciated. Thanks! Dan [[alternative

Readers, For a part of the 'plot' command: ...ylab=expression(paste('rate (',degree~C^-1,')'))... Is it possible to introduce 'thinspace' (e.g. '\thinspace' in LaTeX) between the degree (?) sign and the centigrade (C) symbol? -- r2151

Hi all, I want to draw a line with the values of x marked in X axis. I tried with x <- c(0,6,12,18,24,30) #coordinates of points x y <- c(2,5,7,5,7,16) #coordinates of points y plot(x,type="n",xlab="Months",ylab="Y values",main="main",ylim=c(0,16),xlim=c(0,30)) lines(x,y) The graph shows by default an increment of the sequence in x axis that

Hi all, I'd like to use superscript or subscript in the axis label of a graph. Is that possible in R? For instance in xlab="Ce (mmol/m3)", I'd need the "3" of cubic meter in superscript.

Hi, I created the script below to plot multiple graphs. It seems to work pretty well (see BYX7) except when the max value for catch or TACC is very small. In this case the x-axis labels are removed from the x-axis (see BYX10). I can't figure out why given that y co-ordinate for the text function is par("usr")[1] - 0. Shouldn't this mean that it is flush to the x-axis? Can

Dear R-users, I was wondering if there was a way to adjust the placement of the axis titles for the last page of a multi-page lattice plot (see example below). Depending on the total number of panels, the placement of these titles might look strange on the last page, if the layout is not adjusted (e.g. in some template code). Any thought on this issue would be welcome. Sebastien

Dear R-Team, I have a problem with writing an array to (for example) a .txt-file. Because of the .txt-file must be read from another programm (OPL ILOG), the syntax of the output must be from a special form: name_of_the_object = [ [1,2, ... ], [1,...], ... ]; I think it's easier to understand with a small example: X<-array(1:4,c(2,2)) should be written as: X = [[1,3],

Dear all,   I have a challenge with a supposedly simple graph (a scatter). I wanted to use R to create a plot/graph with a positive y-axis intercept but it does not seem to give me what I expect to see. As an example, I used the following values   > X<- c(0, 4, 8, 11) > Y<- c(8, 12, 15, 22) then I used the plot function in the base package   > plot(X, Y)   This gave me a graph

Readers, I have tried to use a plotmath command to add the temperature degree sign (i.e. ? C) to the axis label of a graph: > x<-(1:10) > y<-(200:191) > plot(x~y,ylab=expression(*degree~C)) Error: syntax error, unexpected '*', expecting ',' in "plot(x~y,ylab=expression(*" According to plotmath manual, the syntax is '*degree' and I am able to use
