Wishlist: heatmap/image legend (PR#7402)
Full_Name: Elizabeth Purdom
Version: 1.9.1
OS: Windows XP
Submission from: (NULL) (171.64.102.199)
It would be great if heatmap and/or image had the option of printing a legend
bar on it somewhere that would indicate the ranges given by the colors in the
heatmap (i.e. a very small image rectangle with the same colors as in the
heatmap). Because heatmap is using layout, it seems pretty

Graphic legend with mathematical symbol, numeric variable and character variable
Hi,
I'd like to make a legend with a mix of mathematical symbol (tau),
numeric variable and character variables.I have tried :
types<-c("Type 1","Type 2","Type 2")
tau<-c(1,3,2)
legend(x="topright",legend=paste(types,"tau=",expression(tau)))
but it doesn't work: the 'tau' symbol is not written in its 'symbol

Legend titles in log plots broken? (ver. 2.2.1)
Legend titles work in linear plots:
curve(1/x, xlim = c(0, 1))
legend(x = 'topright', inset = 0.04,
legend = '1/x', lty = 1,
title = 'Legend Title')
But when you change to a log plot on either dimension things get screwy:
curve(1/x, xlim = c(0, 1), log = 'y')
legend(x = 'topright', inset = 0.04,
legend = '1/x', lty = 1,

Dear R community
Here my working example

Legend on graph
Hi,
I have a problem when I want to put a legend on the graph.
I do:
legend("topright", names(o), cex=0.9, col=plot_colors,lty=1:5, bty="n")
but the legend is writen into the graph (graphs' top but into the graph),
because I have values on this position. How can I write the legend on top
the graph without the legend writes on graph's values.
Thanks.

Creating a Legend
Dear all,
I'm trying to create a legend for my graph. I hope to have the title as "Land Use Type" and the two elements being "Urban" and "Rural" with a red point and green point respectively. So far I have the following command, but obviously it isn't correct:
> legend("topright", title="Land Use Type", cex=0.75, pch=16,

Mixing lty specifications in legend
Hi all
I have a plot with lines, one specified as (say) lty=1,
using standard line types, and another as (say) my
own spec: lty="51".
I can't get legend to display both. Toy example:
> plot(1~1)
> legend("topright", lty=c("51",1), legend=c("My own","Standard"))

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

Error in documentation for ?legend
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)

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

Tables in legend
I need to create a legend for a simple scatter plot in the following
format.
This is Blah1 number1 number2
This is Blah2 number3 number4

This is Blah6 number11 number12
I looked up these help pages and found the following solution.
lStr<-c(Blah1, Blah2,....Blah6, number 1, number2, ...number12)

Legend
Hi everyone.
I have a linear regression where I retrieve the R2 like this:
r2 = sprintf('%4.2f %s',(summary(reg1)$r.squared))
In my figure I have a legend where I would like to add that R2 value to the
legend text.
Something like: My text R^2 = r2
legend('topright', inset = .05, title='light ratios', pch = c(21),
c(paste('Green/Red', R^2, '=', r2)),

Legend vanishes when placed outside the graph
Hello everyone,
i’ve got a problem with my diagram’s legend. I know i should be able to figure it out by reading the ‘plot’ and ‘legend’ reference. However nothing works so it would be kind if anyone could point me to the necessary parameters.
The problem is that i’m moving the legend using the ‘inset’-parameter so it does not overlap with the graph. However it vanishes outside the graph, so

Howto? plot legend with no line behind the points
Hi R-help,
We are using R 2.2 on Win XP and have a detail question on how the
legend can be optimised.
We use the following;
-> plot(,type="b",...)
The lines in the plot do not cross the points. How can we obtain the
same effect in the legend? (points without a line through them..)
We tried setting the pt.bg to white but this did not help.
See script below.
thanks,

Plot legend
Dear All-
I am trying to create a legend where the first 9 terms are represented as pch=16 in one column (which I am able to do); but, I would like the last two terms in that column to be 'lines" (which are black and red - just as it looks like in the plot). I have read through many help pages and searched the help listserv, but haven't figured this one out yet. Does anyone have

'...' passed to both plot() and legend()
Dear R-devels,
I'd like to create a plot method for a class of objects that passes
the '...' argument to both plot() and legend(), e.g.,
x <- list(data = rnorm(1000))
class(x) <- "foo"
plot.foo <- function(x, legend = FALSE, cx = "topright", cy = NULL,
...){
dx <- sort(x$data)

net classification improvement?
Greetings,
I have generated several ROC curves and would like to compare the AUCs.
The data are cross sectional and the outcomes are binary. I am testing
which of several models provide the best discrimination. Would it be most
appropriate to report AUC with 95% CI's?
I have been looking in to the "net reclassification improvement" (see
below for reference) but thus far I can only
