Re: [R] Second y-axis --- alternative to par(new=
What you need to do is to specify that you don't want labels on the second plot: ## (2) Does plot points where (x-axis) they should be xlim - range(x1) plot(x1, y1, type=l, xlim=xlim) par(new=TRUE) plot(x2, y2, type=p, xlim=xlim, xlab='', ylab='', axes=FALSE) axis(4) On Wed, Oct 7, 2009 at 4:29 AM, Rainer M Krug r.m.k...@gmail.com wrote: Hi is there an alternative to par(new), for ading data to a plot for a different y-axis?

Thanks - but if I want to have the histogram with counts (freq=TRUE), then
I have exactly the situation I was talking about - sorry for not being
clear:
x - rnorm(200)
hist(x, col = blue, freq = TRUE)
lines(density(x), col = red, lwd = 2)
i.e.
left y-axis (histogram): count
right y-axis (density estimate): probability density
When adding a second y-axis, I always rescale the plot with a call to
plot.window() rather than par(new=T). This rescales the plotting area while
still allowing low-level plotting functions like lines and points to be
executed:
x - rnorm(200)
hist(x, col = blue, freq = TRUE)
# recovering par('xaxp') uses the original x limits.
plot.window( xlim = range( par('xaxp')[1:2] ), ylim = range( density(x)$y ))
lines(density(x), col = red, lwd = 2)
Hope this helps!

Actually, I misspoke. I believe the following is the voodoo you want for
exactly recovering the original xlimit:
plot.window( xlim = range( par('usr')[1:2] ), xaxs = 'i', ylim = range(
density(x)$y ))
Basically, par('xaxp')[1:2] only returns the extreme values of the tick
marks on the original x-axis-- using these can still cause points not to
line up. par('usr')[1:2] returns the coordinates of the left and right edges
of the plot screen. setting xaxs to 'i' causes R to use the xlimit exactly
as given and not to pad it by 4% in an attempt to make it pretty.
Good luck!

[R] second y-axis in lattice xyplot
Dear R-help, I recently discovered lattice xyplot, but have been struggling with plotting a second y-axis. I am able to do this with plot() but can't figure it out in xyplot. Any help would be appreciated. I have found help on adding a second Y-axis when the data is all part of the same data frame, but I have two different data frames. Both data sets are being plotted against Date. However the first data set only plots a few points on select dates whereas the second data set is plotted daily. I would like to plot them both with the same x-axis, but separate (labeled) y-axes. Is this possibly in lattice xyplot without too much hassle? Or am I better off plotting with plot()? #The first data set plot: trellis.par.set(superpose.symbol = list(cex = 1.3, pch = c(15,0,17,2), col=c(blue,blue,red,red)) ) xyplot(melt ~ Date, data = df1, groups = si, col = c(blue,blue,red,red), pch= c(15,0,17,2), type = 'p', auto.key = list(points = TRUE, lines = FALSE, x=0.8, y=0.15, corner = c(0,1)) ) #The second data set plot: xyplot(AT ~ Date, data = df2, type = 'o', lty = 1, col = black ) Example data: #df1: Date - as.Date(rep(c(2008-04-27,2008-05-02),each=4), format=%Y-%m-%d) si - factor(rep(c(SO,SF,NO,NF),2)) melt - c(4.7,7.4,17.8,30.8,2.2,11.7,10.1,17.3) df1 - data.frame(Date, si, melt) #df2: Date - as.Date(c(2008-04-27,2008-04-28,2008-04-29,2008-04-30,2008-05-01,2008-05-02), format=%Y-%m-%d) AT - c(7.4,4.5,3.2,2.1,2.0,1.1) df2 - data.frame(Date,AT) Thank you very much for your time.

[R] Second y-axis
Hi list,
In the following code, how can I place the percentage label away from
numbers in the second y-axis (lets say all should be inside plot area)?
Thanks
