math symbol + value of a variable in legend.
Hi R users: I will like to have a legend with math symbols and also with the value of a variable. But I cannot obtain both at the same time (symbol + value of a variable): Here is a reproducible example: m1<-5 m2<-12 plot(1:5,1:5,type="n") legend("topleft",legend=c(paste(expression(mu),"=",m1),expression(paste(mu,"=",m2))),lty=1:2) Thank you for

Array of legend text with math symbols from predefined variables
Hello, I am trying to include legend text with math symbols from a predefined character variable that is read in from a file. ? If there is only one line of text in the legend, the following, although cumbersome, works for me: ? > LegendText = " 'U' [infinity], '=10 m/s' "?? # (read in from a file) ??> LegendName = paste("bquote(paste(",LegendText,

difficulty with R expressions in text/legend
hi, i'm trying to prepend some plain (i.e. unevalutated) text to a typographically evaluated R expression in a legend(...) call. here's a working legend(...) call that is close to what i'd like (where x and y are returned from an lm(...) call): legend("topleft", legend = c(bquote(R^2 == .(summary(x)$r.squared)), bquote(R^2 == .(summary(y)$r.squared))), fill =

Multiple expressions, when using substitute()
expression() accepts multiple expressions as arguments, thus: plot(1:2, 1:2) legend("topleft", expression(y == a * x^b, "where "* paste(y=="wood; ", x=="dbh"))) Is there a way to do this when values are to be substituted for a and b? i.e., the first element of the legend argument to legend() becomes,

Smart legend ???
Hi, all: Is there an automatic smart legend for R? Since my R code is running in a row, which will produce a bunch of R plots in a single run, some of the produced plots are really "ridiculous". Because my legend is fixed to "topleft", sometimes, which occludes the key parts of the figure/plots, but most of the time, the legend works just fine. I'm wondering is there a

question about formula for lm
Dear all; Is there any way to make this to work?: .x<-rnorm(50,10,3) .y<-.x+rnorm(50,0,1) X<-data.frame(.x,.y) colnames(X)<-c("Xvar","Yvar") Ytext<-"Yvar" lm(Ytext~Xvar,data=X) # doesn't run lm(Yvar~Xvar,data=X) # does run The main idea is to use Ytext as input in a function, so you just type "Yvar" and the model should fit....

weird behavior of nsmall in format

Change the text size of the title in a legend of a R plot.
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.

Can an xyplot() plus legend be saved as an Enhanced Windows Metafile (EMF)?
I am trying to save some graphical output including a legend in the Windows Enhanced Metafile (EMF) format. This fails when xyplot() is used rather than plot(). Here is a simple example: require(lattice) a <- c(1:10) b <- c(2,4,5,2,3,5,7,8,9,5) # Output can be saved (or copied to the clipboard) as a Windows EMF image file # from the Graphics Device output window. plot(a , b)

Barplot legend position
Dear useRs, I'm trying to create a barplot like so: x=matrix(1:10,2,5) barplot(x,leg=c("left","right"),besid=T) The legend is placed in default position topright, however the data are plotted there too. I tried controlling the legend position by adding x="topleft" but this results in an error that x matches multiple formal arguments. Leaving out the legend

However, I cannot add line legend and point legend together. The code looks like the following.

base::format adds extraneous whitespace for some inputs
Dear R Core Team, First of all, thank you for your amazing work on developing and maintaining this wonderful language. I just stumbled upon the following behavior in R version 3.6.0: format(9.91, digits = 2, nsmall = 2) format(9.99, digits = 2, nsmall = 2) yield "9.91" and " 9.99" with an extraneous whitespace. My expected output for the second command is

Full_Name: Elizabeth Purdom Version: 1.9.1 OS: Windows XP Submission from: (NULL) (171.64.102.199) It would be nice if legend had the option of some default locations you could choose instead of entering specific coordinates, like "topleft", "topright","topcenter", etc. based on par("usr") coordinates. I know I've wanted it so often I've made my

legend with mixed boxes and lines (not both)
Hi, I seem to be unable to get a mixed legend that has lines *or* polygons (not both). For example: ppi <- seq(0,2*pi,length.out=21)[-21] frame() plot.window(ylim=c(-5,5),xlim=c(-5,5),asp=1) polygon(cos(ppi)*4+rnorm(20,sd=.2),sin(ppi)*4+rnorm(20,sd=.2), col="green",border=FALSE) polygon(cos(ppi)*2+rnorm(20,sd=.1),sin(ppi)*2+rnorm(20,sd=.1), col="blue",border=FALSE)
