...e 'panel.dotplot' call (commented) generates the error 'Error in NextMethod("[") : argument "subscripts" is missing, with no default'. The other problem is that the colors alternate between the levels of the 'site' variable, rather than 'year'. barley$yield2 <- with(barley, yield + 5) dotplot(site ~ yield | variety, data=barley, groups=year, yield2=barley$yield2, col=c("gray", "black"), panel=function(x, y, subscripts, yield2, ...) { ## panel.dotplot(x, y, ...) panel.segments(x, as....

How to show panels for factor levels of conditioning variables which do have no values? E.g. there are panels for "Grand Rapids" when they have values: data( barley ) with( barley, dotplot(variety ~ yield | year * site, layout=c(6,2) ) ) There are no panels for "Grand Rapids" when there are no values for "Grand Rapids": my.barley <- subset( barley, ! ( site == "Grand Rapids" ) ) with( my.barley, dotplot(variety ~ yield | ye...

Suppose I wanted to plot the barley data like this: dotplot(variety ~ yield | year+ site, barley, strip = strip.custom(style = 4)) The factor levels are far too long for that to be useful. I can overcome that problem if I shorten the levels like this: dotplot(variety ~ yield | year + site, barley,...

x.fun <- function( formula, data ) dotplot( formula, data ) x.grp <- function( formula, groups, data ) dotplot( formula, groups, data ) data( barley ) > x.fun( variety ~ yield | site, data=barley ) # no problem > dotplot( variety ~ yield | site, groups=year, data=barley ) # no problem > x.grp( variety ~ yield | site, groups=year, data=barley ) object "year" not found # that's my error, so I do: > x.grp( variety ~...

Hi R Users, I'm trying to re-order the "site names" ("Waseca", "Morris", ...). I'm using following code: libarry(lattice) barchart(yield ~ variety | site, data = barley, groups = year, layout = c(6,1), aspect=.7, ylab = "Barley Yield (bushels/acre)", scales = list(x = list(abbreviate = TRUE, rot=45, minlength = 5))) Can anyone help please. -Gary [[alternative HTML version deleted]]

...in barchart. I guess I'm still not understanding how to piece together multiple panel arguments, especially when "groups" is specified. Example: I want to be able to add the value of "yield" to each section of each bar in this graph: barchart(yield ~ variety | site, data = barley, groups = year, layout = c(1,6), stack=TRUE, ylab = "Barley Yield (bushels/acre)" ) To do this, I add my panel function: barchart(yield ~ variety | site, data = barley, groups = year, layout = c(1,6), stack=TRUE, ylab = "Barley Yield (bushels/acre)", panel = function...

How can I add an extra column containing the rank to a ragged array indexed by more than one grouping factors? E.g. with the barley dataset: How can I to add an additional column ``rank'' containing the rank of the ``yield'' of the different varieties in relation to the indices ``year'' and ``site'' to the barley dataframe? I achieved to calculate the ranks with: rank.lists <- with( barley...

Hi, I have a barchart very similar to the example on the function documetation, however, I want to sort the bars according one group in one panel. Reminding: library(lattice) barchart(yield ~ variety | site, data = barley, groups = year, layout = c(1,6), ylab = "Barley Yield (bushels/acre)", auto.key=list(), scales = list(x = list(abbreviate = TRUE, minlength = 5))) I want to sort the yield value, in "waseca" site (e.g.), according the group of...

Dear R-users, i encountered some problems when trying to adjust the line width of the axes and stripes in a plot created with ggplot2. I use the "barley" dataset of the lattice package to illustrate my problem: library(ggplot2) library(lattice) barley[["SD"]] <- 5 limits <- aes(ymax=barley$yield + barley$SD,ymin=barley$yield - barley$SD) p1 <- ggplot(barley,aes(fill=year,y=yield,x=variety)) p2 <- p1 + geom_bar(positi...

...uild a chart. I have a problem with setting different x-axes. Some x categories are missing but they are display and I don't want. I use scales = list(y = "free",x="free") but it works only for y-axes. Simple example: package(lattice) barchart(yield ~ variety | site, data = barley, groups = year, layout = c(1,6), scales = list(y = "free",x="free"), auto.key=list(rectangles = TRUE, space = "bottom"), ) Let's assume that in the first panel 'Waseca' the category 'Velvet' are not available in da...

...corresponding levels of the conditioning variable(s). Note that, if there is more than one conditioning variable, you will need more than one subsetting index. For example, taking this plot with two conditioning variables and 12 panels in total ... dotplot(variety ~ yield | year * site, data=barley) ... this produces three pages ... dotplot(variety ~ yield | year * site, data=barley, layout=c(2,2)) ... and this produces the second page (both panels for the first conditioning variable and the third and fourth panels for the second conditioning variable) ... dotplot(variety ~ yie...

Hi, how can I change the plotting symbol for the groups in a trellis panel dotplot. My graph is similar to: library(trellis) dotplot(variety ~ yield | site, data = barley, groups = year, key = simpleKey(levels(barley$year), space = "right"), xlab = "Barley Yield (bushels/acre) ", aspect=0.5, layout = c(1,6), ylab=NULL) I'd like to plot the different years with different symbols (eg. one with pch=19 the...

Dear list, is it possible to change the background color of dotplot's points? I tried in many ways but unsuccessfully Thanks in advance Gianandrea require(lattice) dotplot(variety ~ yield | site, data = barley, groups = year, pch=21) dotplot(variety ~ yield | site, data = barley, groups = year, pch=21, bg=c("2","3")) ??!!! -- View this message in context: http://www.nabble.com/dotplot-points-color-tp22099530p22099530.html Sent from the R help mailing list archive at Nabble.com.

All, On p.52 of Deepayan Sarkar's Lattice book there is a nice plot of showing residuals with median lines superimposed or various groups: library("lattice") stripplot(sqrt(abs(residuals(lm(yield~variety+year+site)))) ~ site, data = barley, groups = year, jitter.data = TRUE, type = c("p", "a"), fun = median) Suppose we wanted to make a similar plot for a numeric x-axis. Is there any way to do this with stripplot or does one have to xyplot and presumably panel functionality to get the median line? This does not...
