similar to: Add an arrow to a plot

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!

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 Jim, Thanks again! I do want the arrows at the bottom (beneath the map). This is what I am doing: # Draw the map eps_europe <- mapCountryData(n, nameColumnToPlot="eps_score", mapTitle="EPS Score - Europe",colourPalette=colourPalette, catMethod="fixedWidth", missingCountryCol = "white", mapRegion="Europe", addLegend=FALSE) # ISO3 codes on

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.

Hi Milu, There is a two-headed arrow on the image you sent, and it seems to be where you specified. Did you want it beneath the map, as: par(xpd=TRUE) arrows(-22,54.75,-22,74,code=3) par(xpd=FALSE) Jim On Tue, Apr 12, 2016 at 7:58 PM, Miluji Sb <milujisb at gmail.com> wrote: > Dear Jim, > > Thanks again!

Hi Milu, I just realized that by "the bottom of the map" you may mean "beneath the map", in which case you should use: par(xpd=TRUE) arrows(...) par(xpd=FALSE) Jim On Mon, Apr 11, 2016 at 11:50 PM, Miluji Sb <milujisb at gmail.com> wrote: > Dear David, > > Thank you very much for your replies!

Am doing some vector plots with the arrows() function. Works well. But what I need to do is supply an arrow for scaling for the reader. I need to plot an arrow of some known magnitude somewhere on the page (preferably outside the bounds of the plot, so that it can be seen clearly) with some text underneath it that says, for instance, "10 kg-m/sec". Any ideas? Thanks.

Hi all if I plot a graph on R, I press on the plot Export/Save Plot as Image.... I change name on "File name:" I select Directory....Bibliotecas\Documentos And select Width 800 and Height 800 And finally save in format JPEG It is posible to "type" code so that I can run my function and it is not necessary to make it manually? Thanks in advance. [[alternative HTML

Hi all, I have the next problem: I have a matrix with size 8,000,000x18. My personal computer...blocks...so I have cut my original file into 100 different file. I have written a function that should be run on each of this file. So imagine I need to read data from q1 to q100 file data<-read.table("q1.txt",sep="") and each time I read 1 file execute my personal function

Hi r-users, I would like to add a plot of vertical line segment with arrow from (77,.6) to (77,0) and also a horizontal  line segment with arrow from (0,0.6) to (77,.6) .  So far this is what I have: plot(sq, cdf, type="l", lwd=4,col="blue",xaxs="i",yaxs="i", xlab= "Rainfall (mm)", ylab= "Random no.", main="Random number  and

Dear David, Thank you very much for your replies! I didn't know about par('usr'). I get different coordinates though: [1] -19.75966 54.75966 33.60000 71.40000 But the arrow is not at the bottom of the map. I will keep playing with this. Thanks again!

Dear David, Thank you for your answer. Sorry for the embarrassing mistake. However, even with when I generate a map for the whole world using: eps <- mapCountryData(n, nameColumnToPlot="eps_score", mapTitle="EPS Score",colourPalette=colourPalette, catMethod="fixedWidth", missingCountryCol = "white", addLegend=FALSE) And then use:

Hi, I just compiled R on solaris. Everything seems to run fine. Except, the up and down arrows don't take me through the history.

I would like to have arrow heads at the end of my axes, since I am plotting variable where the absolute amount is irrelevant, there is not supposed to be numbers on the axes. An imperfect example: plot(rnorm(10),bty='l',xaxt='n',yaxt='n',ylab='',xlab='',type='l') abline(h=0) Like this but without, the xaxis and with arrrowheads More like this in

I didn't try it in Rstudio until just now (and I don't remember that you ever mentioned RStudio as a possible issue.) The plotting I see in the default graphics Rstudio

Forgot to copy the list Dear Jim, Thank you for your reply. I must be doing something wrong, If this is my command to plot a map of Europe: eps_europe <- mapCountryData(n, nameColumnToPlot="eps_score", mapTitle="EPS Score - Europe",colourPalette=colourPalette, catMethod="fixedWidth", missingCountryCol = "white",

Hello David, This is exactly what I want but I still can't get the arrows. R and R studio is updated. Thanks again!
