R 2.15.1 OS X (MLion) Colleagues, I am aware that changes in mfrow / mfcol in par() affect cex (from help: In a layout with exactly two rows and columns the base value of ?"cex"? is reduced by a factor of 0.83: if there are three or more of either rows or columns, the reduction factor is 0.66). I generate a multipage PDF in which mfrow varies such that cex is impacted. This affec...

Hello, All: ????? I'm unable to control the font size in plots to svg.? Consider the following: svg('cex-svg.svg') cex. <- 5 plot(1:2, cex.axis=cex.) text(1:2, 1:2, c('as', 'DF'), ????????? cex=cex.) dev.off() ????? When I open this in Gimp 2.10.4, the font size is tiny.? I also tried: svg('cex-svg.svg', width=15, height=15, pointsize=24) cex. <- 5 plot(1:2, ce...

...am using mtext instead of the ylab argument in some plots because i want to move it away from the numbers in the axis. However, the text in the X axis, for example: par(mar=c(5, 5.5, 4, 2)); plot(data, main="plot name", xlab= 'X axis', ylab="", font=2, cex.lab=1.5, font.lab=2, cex.main=1.8); mtext('Y axis', side=2, cex=1.5, line=4, font=2); This works fine, but if I then set par(mfrow=c(3,2)); the text produced by mtext becomes much larger than the text "X axis" produced by plot, despite their having identical cex specifi...

.... I used strwidth and strheight to compute the size of the box which is plotted with rect: z <- rnorm(10) # horizontal text works plot(rnorm(10)) x1 <- 5 y1 <- 0 label <- "Label" cha <- paste(" ", label, " ", sep = "") xh <- strwidth(cha, cex = par("cex")) yh <- strheight(cha, cex = par("cex")) * 5/3 rect(x1 - xh/2, y1 - yh/2, x1 + xh/2, y1 + yh/2, col = "white") text(x1, y1, cha, cex = par("cex")) Now I would like to do the same with rotated text. I found two solutions: - modify the par(&quo...

Hello, Is it possible to change the text size of the title in a legend of a R plot? I tried to directly change the title.cex argument but it seems not to work. Trying : Horizo <- c(1,2,6,10,20) legtext <- paste(Horizo,sep="") legend("topleft", legend=legtext,col=col,text.col=col,lwd=lwd, lty=lty,cex=1.1,ncol=3,title = "Horizons",title.col ="black",title.cex=1.4) gives the...

I've had a chance to read the source more thoroughly. The chain of events is as follows: 1. Local function `plotts()` is defined with argument `cex` that defaults to `par("cex")` 2. `...` is passed to `plotts()`. If "cex" is an element in `...`, inside `plotts()` the variable `cex` is assigned thereby (overriding the default arg). Importantly, this means that the element "cex" is captured and _removed_ from `....

...ss your "syntax checking" for a legal e-mail address. The bug is easily reproducible on my machine as follows: ## start # generate some data y <- arima.sim(list(), 150) # this will definitely dispatch to a ".ts" method class(y)[1] == 'ts' # compare and note that `cex = 0.5` has no effect plot(y, type = 'b', pch = 16) plot(y, type = 'b', pch = 16, cex = 0.5) # it works if `y` is coerced back to a regular vector plot(as.numeric(y), type = 'b', pch = 16, cex = 0.5) # another way to see the issue plot.ts(y, type = 'b', pch = 16, ce...

using R 1.2.1 under LinuxPPC, using the default X11 graphics device, i can't get the cex= argument for plot() and title() to have any effect. works for text(), though. the text size for plot() and title() _is_ correct if par(cex=size) is called first. oddly, mtext() seems to pay attention to cex=, but to ignore the value set by par(). for example, > plot(1:5, 1:5, main="M...

Right, that's my point. The help page mentions a `title.cex`, like I said; saying that `cex` sets the default `title.cex` sure implies to me (and presumably to the other people whose discussion I linked) that a `title.cex` parameter exists. Since no such parameter exists, this bit in the documentation is misleading (suggesting that there is a `title.cex` pa...

...with a fixed circle and with a series of point of different size. Here is a "simplified" example: angle<-pi/180*c(0:360) x<-seq(0,2,by=0.2) y<-seq(0,2,by=0.2) z<-seq(0,1,by=0.1) par(pty="s") plot(-2:2,-2:2,type="n") lines(cos(angle),sin(angle)) points(x,y,cex=z) The size of the points compared to the circle (of radius 1) is important and bears a meaning. But instead of having 11 points with increasing size, I only obtain points of the same size when cex=0.1/0.2/0.3/0.4 or cex=0.5/0.6/0.7 or cex=0.8/0.9/1.0. Please, does anyone know if there is a way...

...question is what is the best method to create plots in R with their final physical sizes? I would like to create a good-looking figure by starting with let’s say win.metafile(“some.emf”, 3.35, 2) . Of course all defaults will produce something unreadable, so I have to scale down everything with cex at least, and probably with lwd changes. I’ve tried something like below. But dashed (and all other) lines are still too thick, plotting symbols are undistinguishable etc. And in general it looks like a mess to override all possible values. Is there a better way to downscale whatever is being p...

> use > > par(mfrow=c(2,2), cex = 1) This does work as written. But when I first checked single-call setting, an mfrow change to cex in the same call superseded cex=1; hence my suggestion to use separate calls to par(). Further checking confirms that the result of a call to par is dependent on argument specification order in th...

There appears to be a mismatch between the documentation and behavior of title(), or at least a clarification is in order. The documentation says you can pass extra arguments from par() as "...". However, cex at least is ignored. Later on in the documentation it becomes clear that you can specify these extra parameters as part of a list. I wouldn't say this is necessarily a bug (and there's certainly a way to do what you want, if you read the rest of the documentation), but I will say it didn...

Dear List, This is an embarrassing question, but I can seem to make this work…How do I change the font size on the xlab and on the numbers shown in the x-axis on the time series plot below. The arguments cex.lab and cex.axis do not seem to be 'passing' to the plot function. plot(ts(rnorm(100), start=2004, freq=12), ylab="RQI", xlab="My X lab", col="black", cex.lab=0.1, cex.axis=0.7) Thanks, Axel.

To whom it may concern: The help page for ?legend refers to a `title.cex` parameter, which suggests that the function has such a parameter. As far as I can tell, though, it doesn't; here's an example: > plot(1,1) > legend("topright",pch=1, legend="something", title="my legend", title.cex=2) Error in legend("topright&quo...
