similar to: arrows or graphics below axes?

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!

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

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.

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, 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, I try to put an arrow to a filled.contour plot. I make this: filled.contour(volcano, color = terrain.colors,key.axes=F) arrows(0.95,0,0.95,1,lwd=2) This work, but the problem is that I find the coordinates at random try, for other graphic with other scale is other fight with coordinates. Anybody know a more easy or more generalized way to make this? Somethink like this

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 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 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

Hello forum! As the subject indicates, I am trying to make a barplot and would like my column names to be in bold. Is this possible in R without having to make my column names in mtext? Any help would be much appreciated. The code I am using is as follows. par(mar=c(3,8,2,2)) par(adj=.5) par(font=2) par(oma=c(3,3,3,3)) par(xpd=TRUE) Blot<-matrix(c(25.2995, 0.7625, 25.6135, 36.5770,

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,

Hello everyone, I have successfully made an error bar graph using the points() command with the arrows() command to maually add on the standard errors. However, one slightly annoying feature of using this method is that the points dont line up exactly with the arrows (if you look carefully the points are never perfectly in the centre of the arrow), even when you move the arrows around in an

Hi there, I produced a plot using the following codes: y<-rnorm(1000, 2, 0) x0<-c(0, 0) y0<-c(0, 0) y1<-c(0, 1) x1<-c(0, 4) plot(density(y), ylab="Abundance of species", xlab="Environmental gradient", main=" ", xlim=c(0, 4), ylim=c(0, 1), lty=2, col=4, xaxt="n", yaxt="n", frame.plot=F) lines(x0, y1) # add an axis

Hi, I would like to draw arrows in a classic 2D plot. Which package should I use? is there R base functions that do job? On google, I could not find any useful discussion about this topic, except a link to the function 'grid.arrows' of the grid package. My problem is I would like to draw arrows at the edge of circles drawn by the 'symbols' function. Maybe there is already a

Greetings, I would like to add 3D arrows (i.e. arrow-headed vectors linking X1Y1Z1 to X2,Y2,Z2) to a 3D plot; ideally the sort of plot that can be rotated interactively. Is this possible using plot3d, or another 3d plotter in R? While it is easy to draw segments in plot3d (e.g. below), I haven't figured out how to add arrow heads, or to create 3d arrows from scratch. ##two headless

Hi, all. I'm sure this is a simple question, but I'm having problems figuring it out myself... I have a table: > currenttable <- table(junk[-1],junk[-n]) > currenttable bar foo junk bar 2 2 0 foo 1 0 0 junk 0 0 1 and I'd like to know the result of the cell currenttable(bar,foo). what is the best way to get that result? thanks!

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.
