similar to: Poor documentation for "adj" and text()

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: >

Thanks Ulrich for sharing your experience. I'm attaching a patch which tries to address the issues you raised. I agree with you in principle, but I think it makes sense to leave some details under "Details". However, the descriptions in "Arguments" should give enough information that a user can get the function to do something predictable in at least one situation, and I

Dear all, Our quite basic function mtext() does wrong adjustments in some parameter configurations. This gets obvious when using multi line texts: There is no way to properly adjust text perpendicular to axis 2, for example. Best Jens Oehlschl?gel m <- matrix(1:9, 3) colnames(m) <- c("several\nlines", "several\nlines", "several\nlines") par(mfrow=c(2,2))

Dear R-users moving from Splus to R (under Windows), I notice that command "srt" within a plot in the original Splus code is ignored by R. For example, if a plot something and then include the line of code axis(1, at=Time, labels=Text, srt=45, adj=1) the srt=45 command within the axis() command fails to draw Text at 45 degrees on the x-axis in R but it works properly in Splus. I will

Hello, I remarked that the function ## Default S3 method: text (x, y = NULL, labels = seq(along = x), adj = NULL,pos = NULL, offset = 0.5, vfont = NULL,cex = 1, col = NULL, font = NULL, ...) accepts vectors of arguments (of the same length) except for the parameter adj. When passing a vector of information for adjusting the labels, only the first value is taken. Any special reason for this ?

I have a very standard barplot. My labels are too long to be printed horizontally under each bar, so I am using text to put the labels on a 45 degree slant. However, the labels are spaced more narrowly than the bars, so on an 8 vertical bar plot, the end of the eighth label is lined up with the seventh bar. Preferably I don't want to do every text label separately (I'm having this

For R Version 1.1.1 and R-devel (Linux)... Sorry, there's no time to fix myself now {e.g., after starting a new device} : par(las=3); plot(1:10); par(las=1) ; mtext("mtext") Gives a left-adjusted (as for adj = 0) mtext, even if par("adj") is still 0.5 Note that I'm also not convinced that mtext() should follow par("las") as it does in the

?text says "'adj' allows _adj_ustment of the text with respect to '(x,y)'. Values of 0, 0.5, and 1 specify left/bottom, middle and right/top, respectively." But it looks like 0, 1 specify top, bottom respectively in the y direction. plot(1:4) text(2,2, "adj=c(0,0)", adj=c(0,0)) text(2,2, "adj=c(0,1)", adj=c(0,1), col=2) #the red

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

Using a line width > 1 results in not only a thicker line but also some fuzz in the other direction, as shown in this example program. You will see that the thick vertical black lines extend below the gray scale horizontal lines. Does anyone know whether this is intended or is it a bug? The application is for displaying a correlation matrix (here just some random U(0,1)s). Thanks -Frank

I'm trying to format text on a plot such that the string is vertical but the letters are horizonal. I tried text(1,1,label="output", srt=270) This gives the string rotation I want, but that rotates the entire "output" so the letters are also rotated. I've also tried text(1,1,label="output", srt=270, crt=270) to no avail. par()$crt doesn't seem to affect

Hi, I'm trying to customize a window with 2 graphs. I'm able to do the first one with something like this general example par(mfrow=c(1,2),cex.axis=0.85,cex.lab=0.80,mai=c(1.3,1,0.5,0),las=3) bplot<-barplot(bar.values,names.arg=cf.names,width=0.5,ylab="% Area held") abline(h=0.3,lty=3,col="red") abline(h=0.1,lty=3,col="blue")

What I want to do is create a horizontal bar chart matrix for a set of data that have a common set of variables (e.g., % of As, % of Bs, etc.) listed on the Y-axis and groups (e.g., Classes) on the X-axis. The key here is that the bars for each individual class plot are "centered" rather than left or right-justified. In archaeology plots similar to this are called battleship curves or

Hi, I have a problem with aligning text which I'm adding to a plot using "mtext". I would like to specify the position of the right hand end of the text string, relative to the device (in the left-right direction). I've been looking at the use of the argument "adj". But this can't be used to specify the rightmost point of the text. Neither does it specify exactly

Depending on the setting of par()$usr, the 'at' setting in mtext(.., adj=0, outer=T) may cause the text to appear in an anomalous position (e. g. in the first instance below, at the left of the plot region rather than at 'at=0' in the figure region), or the text may not appear at all. If one does not set the 'at' parameter the text appears (with 'adj=0') on the

Hi, text()'s pos does handle more dimensional labels, while adj does not - or how can I pass an array to text() and use the adj argument (skyblue text)? plot(-1:1,-1:1) text(c(0,0),c(0,0),c("a","b"),pos=c(1,2),col="red") text(c(0,0),c(0,0),c("a","b"),adj=cbind(c(1,2),c(1,1)),col="skyblue") Thomas

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,

I'm having trouble centering multi-line strip text in lattice. As the code below demonstrates bounding box of the text is centered within the strip, but the first line isn't centered in relation to the longer second line. The "adj" argument to par.strip.text doesn't seem to do much. Suggestions? a=data.frame( x=rep(1:10,2) ,y=rep(1:10,2) ,z=rep(c('First Line\nLonger

Hi, I have been working through one of the examples on the FAQ about rotating the labels on the x axis, I need to do the same but for the y axis. I have managed to change some of the code, but I am still not getting there, there is still something wrong. My syntax is as follows: > par(mar = c(5, 7, 4, 2) + 0.1) > plot(1 : 8, yaxt = "n", ylab = "") > axis(2,
