dear experts, i m very concerned about memory management. would appreciate if you leave me some tips on handling large datasets.. special interset: 1. importing large data from a text file 2. subsequent manipulations in R thanks very much best regards pan yuming -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read

In Version 1.1.0 Under development (unstable) (June 8, 2000) there seems to be a problem with an internal variable w0 in legend that generates the following new error: Error in legend((par()$usr)[1:2], (par()$usr)[3:4], Legend, lty = lty, : Object "w0" not found > -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-devel mailing list -- Read

dear all, i have a matrix and i dont know how to assign names to this matrix. given v is 100x5 matrix, and label -> c("A","B","C","D","E") idealy, names(v) <- label, but it doesnt work for different length if dimnames(v) <- list(1:nrow(v),label), then names(v) return NULL any smart ways? thanks in advance. best regards pan yuming

Hi all I have a question about plotting line types and legends. Here's a short piece of code to demonstrate: x <- y <- seq(1,10) plot(x,y, type ="l", lty="33") lines(x,y+1, lty=1) legend( 8,2,legend=c("lty=1","lty=\"33\""), lty=c(1,"33") ) On my system (see below), the line types in the legend are not the same as in the

Hi: I'm trying to plot dates on the x-axis of a code, but the legend is not being displayed. I receive the following error: Error in match.arg(x, c("bottomright", "bottom", "bottomleft", "left", : 'arg' should be one of bottomright, bottom, bottomleft, left, topleft, top, topright, right, center In addition: Warning message: longer

Hi there, I have the following plot. The circles and the line do not cross in the main plot. But in the legend, the circle and the line cross. I am wondering if there is a way to make the legend look like the plot without crossing. I looked around but did not find a way to do that. Is it doable? plot(x,x^1.5, pch=1, lty=1, type='b') legend(1,25, legend="hello",pch=1,

I'm trying to develop a systematic way of placing legends on (among other things) scatterplots of grouped data. The journals in my field can be very fussy about the placement of figure legends. Typically they want them to be in either of two places - the upper left corner of the plotting area, not obscuring any data points, or outside the plotting area in the lower right hand corner of

Hello, I have a time series plot drawn using 3 different colored lines, each line corresponds to different category group. I'd like to put legends on the plot. I am using "legend" to do this, however, I can either specify lty or col in legend. Will I be able to do the following in the legend box: a solid black line then g1, a solid red line then g2, a solid blue line then g3?

At one point I believe I heard of an R package that would automatically find the most empty space in a plot, and then that answer could then be used to intelligently place a legend. I would like to try to apply that R package to the contrived example shown below, so thank you for any hints or tips that can be provided. x = seq(0, 1000, by = 1) y1_vals<-rnorm(1000, mean = 0, sd = 50)

Hallo R-users, I do not understand how to specify the correct line and symbol types in the legends of a lattice xyplot. This is what I tried, but the line types and symbol in the graph are not seen in the legend. Any help is appreciated. Thanks, Gerrit. library(lattice) s<-rep(1:3,len=10) x<- 1:10 y<- x+s+rnorm(10) d<-data.frame(s,x,y) xyplot(y~x, groups=s,data=d,

Hi listers, I want to make lattice plots xyplots with the indication of legends inside each panel with only the points and the lines actually ploted inside each given panel according to the group(ing) factor. The code below shows what I have achieved so far and I hope will make clear what I want to have. It seems to me that my solution is a very "dirty hack" and there certainly is

Dear All, I am producing a figure with many curves on it. How do I make the legends for all those curves smaller so that it can fit the figure itself? The commands I used for ploting are: plot(x1,y1,col=1,lty=1) lines(x2,y2,col=2,lty=2) ... legend(0.3,0.4,c("name1","name2",...),col=1:20,lty=1:20) Any tips for making the legend fit the figure will very welcome! Thanks! Best,

Hello, placings of legends is sometimes tricky. For placing outside the plot region I found locator to be useful. Unfortunately, the click defines the upper left corner. Is there a way to change this corner (say lower right corner)? Thanks, Christian

Hello, I have difficulties combining boxes and lines in plot legend. I searched previous R-posts and found this (with no solution): http://tolstoy.newcastle.edu.au/R/help/06/07/30248.html. Is there a way to avoid boxes behind the line legends? x1 <- rnorm(100) x2 <- rnorm(100, 2) hist(x1, main = "", col = "orange",ylab = "density", xlab = "x", freq =

I have made a minor hack to "legend" (in R 1.0.0, but I didn't notice any changes to legend in the 1.0.1 NEWS) to allow the legend to be formatted in multiple columns, or horizontally (number of columns <- number of legend items). (I find this helpful when I have lots of legend items and not a lot of vertical space to squeeze the legend into.) (Another hack I've considered

I discovered a little problem when using the Windows NT release of R 1.0.1, and it's still there in R 1.1.0. The boiled down version is this: I want to draw the following plot and put it into a Postscript file: x <- c(1,2,3,4); y1 <- c(1,2,3,4); y2 <- c(2,2,2,2) Fred <- c(1,2) postscript(file="d:/Bob/Papers/IFM/try2.ps") plot(x,y1, type="l")

I am testing out the grid-plots, but get into a problem making a legend. I have a line plot and some points, following the model in grid.plot.and.legend() i manage to get the points correctly in the legend, but what do I do with the line? (Of cource, I can just draw a line at the right location on the plot, but I would prefer to use legend) Morten -- Morten Sickel Norwegian Radiation

Hi List, is sth. like the following possible: legend(x,y,c("A","B","C"), lty=list(1,"42","11")) ? Or: is there a possibility to define a solid line using the "string" mode for lty?

Is there a simpler way then the solution to the one that was posted here? I'm not very proficient with legend, and I don't understand this solution. All I have is two or more lines on one plot that I want to put a legend on and I can't figure out how to do it from the examples. Can you give a very simple example? It does not have to be fancy!! I have never worked with a

I could not find a way to specify the border color of the boxes drawn in a legend, so that the legend can match exactly the colors of the actual plot (e.g. in the case of two superimposed histograms which have different shading and different borders). Indeed, the legend function seems to hard code the color "black" for the borders in this call: rect2(left = xt, top = yt +
