Hello all, How can I increase/decrease the line length for screen wrapping? Currently when I run the following the output appears to wrap at just under 80 columns: > c(1:100) [1] 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 [19] 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 [37] 37 38 39 40 41 42 43 44 45 46 47 48 49

Dear All, I am having a bit of problem using the DBI and RMySQL package. I have already installed DBI but now I want to connect to MySQL. So how do I do it. The CRAN package repository does not have RMySQL windows binary to install from?

Is there a way to stream data into R so that it can be used in a command pipe? Most Unix commands read data via standard input and read the script from the command line. For example: $ seq 1 10 | sed -e 's/^/foo /' $ seq 1 10 | awk '{print "foo " $1}' $ seq 1 10 | perl -lane 'print "foo $F[0]"' In contrast, R seems to read the script

Is there a cheat-sheet anywhere that describes how to do SQL-like manipulations on a data frame? My knowledge of R is rather limited. But from my experience it seems as though one can think of data frames as being similar to tables in a database: there are rows, columns, and values. Also, one can perform similar manipulations on a data frame as one can on a table. For example:

Why am I getting the error "Error: cannot allocate vector of size 512000 Kb" on a machine with 6 GB of RAM? I'm playing with some large data sets within R and doing some simple statistics. The data sets have 10^6 and 10^7 rows of numbers. R reads in and performs summary() on the 10^6 set just fine. However, on the 10^7 set, R halts with the error. My hunch is that

Does R have command or object name completion? R has several functions of modern shells built into it e.g. history mechanism, command-line editing, emacs key bindings. However, it doesn't seem to have command or object name completion. For example, in bash I can begin typing a command and then press the tab key to have the shell fill in the rest of the command (works for environment

I am new to R ( and windows XP ) and am in the process of setting it up I put an options (repos=http://.fhcrc.org") file in my .Rprofile file and it works but that's all I put in and i don'tknow what to put in my .First function. I understand that .Rprofile is used for more general options and .First for options specific to that working directory. would someone mind to send me an

Hi, I am very new to R and I have written the following block of code to generate a gamma distribution for variable x (which is an array) and a function "y" whose array values depend on the individual array values of "x". The code is as follows: n=1000 x=rgamma(n,1.5,2) y=vector("numeric",n) for (i in 1:n){ y[i]=(2937/50000*exp(-1/1000*x[i])/x[i]) } now I want to

Hi, all. I'm trying to automate some regression operations in R leaving the possibility to modify the predictors in the regression. For example, I have saved in a list the results and then exported as a txt file, in which we can modify the predictors, putting for example lm(y~x^2) instead of having lm(y~x) as in the original model. Now, I need to import in R the txt file as a list to

Dear R folks: I wonder anyone has a elegent way of doing what I need to do. I have a data frame called with four columns: V1, V2, A1 and A2: V1 V2 A1 A2 A B 1.2 2.0 A D 1.2 4.0 A C 2.4 2.2 What I need to do is to convert it into the following data frame with a new column x, where x is just the stacked up of A1 and A2 placed with respective V1 and V2 in the first two

Is there any simple way to add text to the x axis in R? I have tried to add simple characters in R without any greater sucess. As an example of what I want to do is the added C in the following "dumb" plot (produced with MacAnova using the option "dumb:T"): ++------+-------+------+-------+------+-------+------+-------++ 1+ :

Hi, I have a query about the maximum length of vector that can be plotted in one go in a postscript driver. Try the following code (in 1.7.0; version details below): t <- seq(from=0, to=4*pi, length=200000) y <- sin(t) postscript(file="o.ps") plot(t, y, type="l") dev.off() If I view the postscript file o.ps in "gv", it takes many seconds before eventually

Hi all, I wonder why there is so little software for carpet plots (german: Rasterdiagramm) (Three dimensional plot (x, y, z), the 3rd dimension (z) symbolized by colourgradients). Besides from one or the other non free software I only found an OpenOffice macro, a combination of Gnuplot and Excel (an Excel macro calling gnuplot) (http://www.johannes-hopf.de/2009/12/carpet-plot-version-1-3/9 and

Okay, going to try this one more time with pine (the GnuPG signing from the Enigmail plugin for Thunderbird keeps getting rejected by sourceforge). Right. Anyway, the documentation (in several places) says the analyze option to use GNUplot is "--residual-gnuplot", when the code actually checks for "--residual-gnu-plot"....extra hyphen. i checked this late last night, but

I'm a scheme and C user generally, I'm a bit wary of the large FORTRAN content of the R language but aside from that issue it seems nice and simple and easy to use. What I want to do is find some GPL software to replace gnuplot, and since R does all the calculating stuff that gnuplot does (probably R is faster though I haven't tested) plus R has quite decent plotting capabilities I

Hello, I am trying to send commands to GNUPLOT to load a .plt file that was generated with a C++ software module called with R, and to replot. I am able to open the program with shell.exec (below) but I am at a loss at what do next. Any suggestions?? shell.exec("C:\\ gnuplot \\ bin \\ wgnuplot.exe") Thanks

Hi there, I'm new to R, coming from gnuplot for the plotting facility... I'm just wondering if there is a equivalent to the fit function of gnuplot in R? If not, s there any good resource on fitting gaussians into a curve? greetings, Stefan

Hello, I'm trying to run R from a webserver, which doesn't have an X server, and produce pngs to go on a webpage, is this possible? I'm doing it in gnuplot with gnuplot> set term png gnuplot> set output With $DISPLAY unset, I get the following error from R: > png() Error in X11(paste("png::", filename, sep = ""), width, height, pointsize, :

Hi, I have some scripts creating GNUplot graphs that I would like to convert to R. It would be a great help if there would be a reasonable converter that takes over plot commands and initial settings and put these into R commands (I'm an R beginner and thus this kind of Kickstart would be helpful). Remark: Asking Google for "gnuplot to R conversion" or similar things does not
