I'm trying to draw an arrow with a curved shaft on the graph as a straight one looks messy on a detailed graph. I've looked in arrows but it doesn't seem to give an option. larrows doesn't look much more promising. I had a look in the archive and couldn't find anything. Any thoughts?

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

The result of > plot(c(-1,1),c(-1,1),type="n") > arrows(0,0,1,1) > arrows(0,0,0,0) is not what I expected. The first arrow is drawn correctly. The second does not collapse to a point but goes from (0,0) off to (-infinity,infinity). I guess something is divided by zero in the internal function.

Hi all, I've been using the arrows() function in plots a lot, but I'm not happy with the appearance of the arrow heads. I understand that arrows () doesn't offer more sophisticated arrowhead shapes like e.g. a filled triangle, possibly with choice of angle at the point. Does anyone know an easy way to achieve this? thanks Hendrik

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

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 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 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 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, 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.

There is a function called arrows() which is an .Internal function. How difficult is it to modify that function to return the xy coordinates for the line "segments" that make up the arrowhead? Brandon Chasco University of Washington ph (206) 221-6768

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 all, for example: > X<- rnorm(1000) > X0 <- 0.899 I want to draw a density distribution plot with a arrow pointer indicating the position of X0, meanwhile, giving out the p-value. any functions? Thanks very much.

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!

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.
