Dear R developers, I would like to have R choose the limits of the y-axis semi-automatically, e.g., zero should be included, but the maximum should be chosen depending on the data. Examples: plot(1:10, 1:10) # selects min and max automatically plot(1:10, 1:10, ylim=c(1, 10)) # manual definition plot(1:10, 1:10, ylim=c(0, Inf)) # this would be a nice feature, i.e. lower y limit = 0 defined manually, upper limit = 10 selected automatically The relevant code from plot.default would have to be modified: old: ylim <- if (is.null(ylim)) range(xy$y[is...

list(...), I would like to zoom in to the leaves of large trees in a dendrogram plot. The playwith package allows zooming by passing xlim and ylim arguments to the plot call (Hmisc does this too I think). But currently stats:::plot.dendrogram does not accept xlim or ylim. So I would like to enable that. In place of the existing code chunk: xlim <- c(x1 - 1/2, x2 + 1/2) ylim <- c(0, yTop) if (horiz) { xl <- xlim...

Dear R users, I want to retrieve "..." argument values within a function.

Hello, When drawing "barcharts", I find it not helpful if ylim[1] != 0 - bars for a quantity of 0, that do not show a length of 0 are quite non-intuitive. I have tried to study > library(lattice) > panel.barchart but am unable to figure out where ylim is taken care of and how one might fix ylim[1] to 0 for barcharts ... Can anyone point out how to...

I am plotting multiple graphs per window with multiple series on each graph. When I try to set ylim I get the error below: Error in ylim[[idx]] : subscript out of bounds Am I incorrectly specifying my ylim list or is this a bug?

Hi together, I always get an error message with using ylim in termplot(), like this: > x<-(1:10) > y<-(10:1) > l<-lm(y~x) > termplot(l,ylim=c(1,2)) Is this a bug, or is there another possibility to do that? Especially, I would like to use term.plot() for gamlss objects. Thanks for your help! Andreas -- Echte DSL-Fl...

There have been various elegant solutions to test for the presence of a particular named parameter within a ... argument, such as if (!is.null(list(...)$ylim)) if ("ylim" %in% names(list(...))) I think I'd have to comment these lines pretty clearly if I wanted to easily follow the code in 6 months time. But I'm still not convinced it is ever a good idea to use this technique in preference to using explicit named arguments. If there...

...reas I know that it cannot be less than (say) 0; and I want to fix the lower limit at 0 in any plot, leaving the upper limit to be assigned by plot() as a result of the computed values. I know I can do this by determining the max() of the data, and then computing a "Ymax" to put in (say) ylim = c(0,Ymax). However, for certain reasons, I would prefer not to have to do this. (And it's just a preference ... ). Whereas one can leave the whole issue of setting both plotting limits to plot(), by not specifying ylim (or xlim), or one can explcitily specify both the upper and lower limits...

Hello, I have found that in smoothScatter it is not possible to reverse the axes plotted (R version 2.9.0) .   It appears that this arises from the hard coding of xlim and ylim in smoothscatter.R in the lines : x <- x[ xlim[1] <= x[,1] & x[,1] <=xlim[2], ]   (line  number 25) and x <- x[ ylim[1] <= x[,2] & x[,2] <= ylim[2], ]  (line number 31) This results in a x being NA if ylim[1] > ylim[2] which results in an error on executing  map &l...

I'd like to make a plot with the axes drawn at the values of xlim and ylim. The default plot draws the axes slightly outside these values. I have been experimenting with the par(mgp) setting, but specifying par(mgp=c(2,0,-1)) gives me "invalid value specified for graphics parameter "mgp".". A more complicated mathod that almost seems to work is doin...

R Version 2.2.0 Platform: Windows When I use barplot but select a ylim value greater than zero, the graph is distorted. The bars extend below the bottom of the graph. For instance the command produces a problematic graph. barplot(c(200,300,250,350),ylim=c(150,400)) Any help would be appreciated. Paul [[alternative HTML version deleted]]

...nux Submission from: (NULL) (194.73.101.157) bxp() allows specifcation of box locations with at=, but neither adjusts xlim= to fit at nor does it respect xlim provided explicitly. This is because bxp() now includes explicit xlim as c(0.5, n+0.5), without checking for explicitly supplied xlim (or ylim if horizontal). This also prevents simple added plots (eg if add=T, with at=(1:n)+0.5, the last box is partly off the plot. The 'offending' code is in bxp: if (!add) { plot.new() if (horizontal) plot.window(ylim = c(0.5, n + 0.5), xlim = ylim,...
