Hi! Could you tell me how I can draw a graph with error bars? Sorry, I don't use R that often and I couldn't find it easily in the documentation.

Hi! How do I specify a filled point in a scatterplot? Their size? plot(x,y) just gives "empty" points like "o". I want a full black point.

Hi! I need to plot two lines on the same graph. I do plot(x,y) then plot(x,z,add=TRUE) but I get the following warning messages Warning messages: 1: parameter "add" couldn't be set in high-level plot() function 2: parameter "add" couldn't be set in high-level plot() function 3: parameter "add" couldn't be set in high-level plot() function 4:

Hi! I would like to read data read with read.table row by row into a c() vector. data<-read.table("test",header=FALSE) for (i in 1:length(data[[1]])) { temp <- ?? do something with temp } data[1,] gives me V1 V2 V3 V4 V5 1 1 -1 -1 -1 0.33 c[temp[1],temp[2]) gives me $V1 [1] 1 $V2 [1] -1 Sorry if that's well known but I can't still figure it

Hi! There is a "musical" note next to the rpm in CRAN and its mirrors and it seems to require some sort of plugin that I don't have. Is there a way around that?

Hi! I want to display 2 graphs with different number of data points on the x-axis. The code below scales them so it seems that testtwo has the same number of data points as testone. How can I fix that? thanks. z<-1:50; x<-1:100; plot(x,testone,type="l",xlab="",ylab="",main="",lty=4,axes=FALSE,ylim=c(-1.0,1.0),cex=1); par(new=TRUE);

I know this has got to be simple, but I have a added an arrow to a graph with: arrows(5,8,8, predict(lmfit,data.frame(x=8)), length=0.1) but its in the wrong position, correcting it and running again adds an new arrow (which is what you would expect) so how do I a) edit the existing arrow, and b) delete it all together As so often seems to be the case, some of the simplist things seem also to

Hi, All. I'm trying to make an arrow pointing to a particular value on the x axis. So, this is pretty much what I want: 20 210 220 230 240 250 260 ... ^ | | any ideas how to do this? I tried a few things (like arrows), but they didn't want to plot outside of the actual "plot" area... thanks for any

Hello Jim, Thanks again. I am getting the two-headed arrow but I cannot seem to get the coordinates right for the arrow to appear beneath the map. These coordinates puts the arrow on the left hand side. Thanks again!

Hi, I'm a beginner using R and I'm modeling a time series with ARIMA. I'm looking for a way to determine the p-values of the coefficients of my model. Does ARIMA function return these values? or is there a way to determine them easily? Thanks for your answer Myriam

I've rolled up R-1.4.1.tgz a short while ago. This is a patch upgrade, fixing the most important bugs that cropped up after the 1.4.0 release. A set of recommended packages which have been tested with R-1.4.1 has been bundled up. Binary distributions are expected to include these packages. You can get the files from the developer site ftp://cvs.r-project.org/pub/CRAN/src/base/R-1.4.1.tgz

hello, ladyes and gentlemans. check this: means<-c(4,6,8) stand.error<-c(0.1,0.3,0.5) now i've strongly tryed to scatterplot the means(y-axis),by showing their sd with the arrow(..,code=3,angle=90) function. The problem is that my x-axis has categorical values (say, factor(x)), and the arrows() can't recognize them as right coordinates. ????? thank you all in advance B.F. insubria

Dear R developers, I want to draw an arrow in a figure with lty=2. The lty argument also affects the edge of the arrow, which is unfortunate. Feature or bug? Is there some way to draw an arrow with intact edge, still with lty=2? Example code: plot(1:10) arrows(4, 5, 6, 7, lty=2) Best wishes, Matthias --

Dear Mr. Baddeley   I just graduated from a Masters in Applied Mathematics on Jun19th. My thesis was about spatial distribution /a nalysis of some trees in a part of  the Congo Basic Forest. In my thesis I used your spatial package in R, and today I'm doing a more deeper study about how we choise the r distance in Function F(). I would like to be able to understand about value of rmaxdefault

Hi Milu, My fault here. As I don't have the data to make the map and try out my suggestions I mixed up the x and y coordinates. Try this: par(xpd=TRUE) arrows(-19.75966,53,33.60000,53,code=3) par(xpd=FALSE) Jim On Tue, Apr 12, 2016 at 10:11 PM, Miluji Sb <milujisb at gmail.com> wrote: > Hello Jim, > > Thanks again.

arrows() seems to hang when either x or y scale of the plot is logarithmic and the arrows requested go beyond the plot (by more than a certain amount). I didn't go into C code to find it, but here's a function that exercises the bug a bit ... arrow.bug2 <- function(y0=1,y1=10,log="y") { plot(c(0.1,1),c(1,10),log=log) arrows(x0=0.5, y0=y0, x1=0.5,

Dear list, I would like to plot arrows with different colors according to arrow length, and also (if possible) with head size proportional to arrow length. The idea is to make a quiver-like plot of matlab with wind speed data. So far, I´ve been able to use different colors, but I need to find a more efficient way to recode arrow length intervals into colors. On the contrary, I can't define

Hi I want to plot an x,y plot something like an scatter plot. I always have the same doubt, were is the last point of my file? Imagine it is a time series so I want the last point to indicate with an arrow (but athomatically if posible). Someone knows if it is posible? Could it be posible to add additional arrows (with a small square with text?) I hope you can comprehead me? I suppose you

Dear R Users, close to the end of this I used wireframe to create a 3D plot from a matrix. The x and y axis tick labels (1-6) for each were created from the matrix being a 6X6 matrix. I need the axis tick labels to be the row and column headings which you can see in the output (mat.x). I have tried several work arounds, but they have not been successful. Thanks in advance. keith rm(list=ls())
