How can I look up the aspect ratio of a plot, so I can use that to correctly adjust the angle of text which is supposed to be parallel to a line in the plot? The following example code works for a 1:1 aspect ratio, but puts the text at the wrong angle if the plot region is short and wide or tall and narrow. I can't find a par() component containing the plot aspect ratio. It will be for

[resent, plus small addition; I do not understand why gmail sent a weird charset.] Dear R wizards: I would love to write a general function that matches the slope of a plotted line in an xy-plot at a particular x,y location. something like x<- (1:10)^2; y<- 40:50; plot( x,y, type="l", xlim=c(0,90) ) srt.at5 = text.at.current.plot.with.slope( x, y, 5); text(

I have a data set that I display using barplot. I don't know what you call it, but when I look at it, it looks like this: > lsu (0,0.1] (0.1,0.2] (0.2,0.3] (0.3,0.4] (0.4,0.5] (0.5,0.6] A 0.052631579 0.000000000 0.000000000 0.000000000 0.000000000 0.000000000 B 0.000000000 0.000000000 0.001007049 0.003021148 0.000000000 0.000000000 E 0.200000000 0.000000000

Hello all. I have a simple barplot with sixteen different segments. When I plot my data, only five or six of the labels are showing in the x-axis. How do go get them all to show? Can I set them at a 45.degree angle? Thank you.

Dear R users, I am encountering a x axis labeling problem on quite basic plots... I use the following code which displays the labels on the x-axis with a 45 degrees angle: p <- plot(myobject1, type="b", col="red",cex=1, lwd=2, axes=FALSE, ann=FALSE, ylim=c(0,70)) title(main="title", font.main=4) axis(side=1, lab=F) text(axTicks(1), par("usr")[3] - 2,

Hello everyone I have problem with axis labels on graphs, I have my code as below: plot(0,0,xlim=c(1,ncol(PA)),ylim=c(1,nrow(PA)),main="Stratigraphic Range",xlab="Time Bins",ylab="Taxa",cex.axis=1.5,cex.lab=2,cex.main=2.5,mgp=c(5,1.5,0),xaxt="n") text(1:(length(strat_name)), y= 0, adj=1, srt=45,labels=strat_name,xpd=TRUE, cex=1) #adds text to x

In the example: x = rep(c(0,0,1,1),4) y = rep(c(0,1,0,1),4) z = c(1,0,1,0,0,0,1,1,0,1,0,0,1,1,1,1) f = as.factor(c(rep("a",4),rep("b",4),rep("c",4),rep("d",4))) levelplot(z~x+y|f,data.frame(x=x,y=y,z=z,f=f)) I noted that the last ("d") plot remains empty. I guess the reason for this is that the values are constant (1), but I consider it more

Hello, is there a way in which I can use text labels rather than numbers on the x axis ticks? I basically have a vector of (say) 8 points and I want to plot these sequentially. Thus the x axis would have ticks at 1 .. 8. Rather than having the labels 1 .. 8 I would like to have some arbitrary text labels. Ideally I would like the labels to be rotated (say at 45 degrees) so that they don't

Dear listserv, Here is my latest formatting problem. I would like to rotate the x-axis labels by 45 degrees on a _barplot_. Apparently this is slightly different from the example given in the R FAQ, which is for rotating the x-axis labels on a scatterplot (http://cran.r-project.org/doc/FAQ/R-FAQ.html#How-can-I-create-rotated-axis-labels_003f). I have adapted that code, as best I could, and

hi all, in R, what's the best way to have a rotated ylab in a graph plotted with either xyplot or xYplot? I tried this but it didn't work. xyplot(y~x,data.frame(x=1:10,y=runif(10)),ylab=list(srt=90,crt=90,rot=90,label="my label")) more generally, how do you output a text at an angle in a lattice graph? what would be a good reference for R lattice graphics? I need more

I searched the forms (i.e., R Search)?and come up with the following suggested link: ?http://cran.r-project.org/doc/FAQ/R-FAQ.html#How-can-I-create-rotated-axis-labels_003f I tried to implement what I believe was being implied by that URL and came up with the below: barplot(WorldPhones[1,], ??????? ylim=c(0, 50000), ??????? axes=FALSE, ann=FALSE, ???????

Hi all, - how can I do a barplot with rotated axis labels? I've seen the example for just a plot in the FAQ, but I'll missing the coordinates to plot my text at the right position beneath the bars. Is there any (easy?) solution? - how can I set the y-axis in a barplot to logarithmic scale? Many thanks in advance! Best Regards Tom --

Rotated text for axis labels should be possible with one of par(srt=90) axis(1,at,labels) par(srt=0) or axis(1,at,labels,srt=90) (or similar with crt instead of srt) None of these works in pre0.65 or in 0.64.2 _ platform sparc-sun-solaris2.7 arch sparc os solaris2.7 system sparc,

Hi All, I am looking for help in rotating species titles produced using the strat.plot( ) function in the rioja package. This function produces a stratigraphic plot of paleoenvironmental data. Currently the titles of each species are plotted vertically while they are typically plotted at a 45 degree angle in other programs. Does anyone have any idea of how to rotates these titles? Below is an

Hi! (I'd like to be able to access your bugzilla, BTW) The documentation for parameter "adj" of text() in R 3.3.3 is hard to understand (unless you know what it does already): "adj one or two values in [0, 1] which specify the x (and optionally y) adjustment of the labels. On most devices values outside that interval will also work." What is the meaning of the values? I

Hello Core Team, I sent this patch over a year ago. It looks like it was sent in response to another user's complaint which echoed some of my own observations about problems in the documentation for 'text'. Did anyone have a chance to look it over? I'd like to get it out of my queue. Thanks, Frederick On Tue, Apr 11, 2017 at 12:01:05PM -0700, frederik at ofb.net wrote: >

Hi all, I'm hoping to add texts into a plot. I'm using text() to do it. I wonder if the text() allow me to make the text vertically printed? Thanks in advance for help, phoebe [[alternative HTML version deleted]]

Hi R-users I'm a relative newbie and uses R mostly for graphical purpose. I have a layout problem when plotting a scatterplot and a barplot using par(new=TRUE). The baseline of the x-axis is not positioned equal for the two plotting functions (see picture) and I have been unable to find out how this is changed. http://www.nabble.com/file/p18025066/pic.jpeg I have added the script if this
