[R] Define pch and color based on two different columns
I am making a lattice plot and I would like to use the value in one column to define the pch and another column to define color of points. Something like: xyplot(mpg ~ wt | cyl, data=mtcars, col = gear, pch = carb ) There are unique pch points in the second and third panels, but these points are only unique within the plots, not among all the plots (as they should be). You can see this if you use the following code: xyplot(mpg ~ wt | cyl, data=mtcars, groups = carb ) This plot looks great for one group, but if you try to invoke two groups using c(gear, carb) I think it simply takes unique combinations of those two variables and plots them as unique colors. Another solution given by a StackExchange user: mypch <- 1:6 mycol <- 1:3 xyplot(mpg ~ wt | cyl, panel = function(x, y, ..., groups, subscripts) { pch <- mypch[factor(carb[subscripts])] col <- mycol[factor(gear[subscripts])] grp <- c(gear,carb) panel.xyplot(x, y, pch = pch, col = col) } ) This solution has the same problems as the code at the top. I think the issue causing problems with both solutions is that not every value for each group is present in each panel, and they are almost never in the same order. I think R is just interpreting the appearance of unique values as a signal to change to the next pch or color. My actual data file is very large, and it's not possible to sort my way out of this mess. It would be best if I could just use the value in two columns to actually define a color or pch for each point on an entire plot. Is there a way to do this? Ps, I had to post this via email because the Nabble site kept sending me an error message: "Message rejected by filter rule match" Thanks, Matt *Matthew R.

Hi Matthew, How about this? library(lattice) xyplot(mpg ~ wt | cyl, data=mtcars, col = mtcars$gear, pch = mtcars$carb ) library(plotrix) grange<-range(mtcars$gear) xyplot(mpg ~ wt | cyl, data=mtcars, col = color.scale(mtcars$gear,extremes=c("blue","red"),xrange=grange), pch = as.character(mtcars$carb) ) Jim On Wed, Apr 10, 2019 at 7:43 AM Matthew Snyder <msnyder424 at gmail.com> wrote:> > I am making a lattice plot and I would like to use the value in one column > to define the pch and another column to define color of points.

[R] Define pch and color based on two different columns
Thanks, Jim. I appreciate your contributed answer, but neither of those make the desired plot either. I'm actually kind of shocked this isn't an easier more straightforward thing. It seems like this would be something that a user would want to do frequently. I can actually do this for single plots in ggplot. Maybe I should contact the authors of lattice and see if this is something they can help me with or if they would like to add this as a feature in the future... Matt *Matthew R.

[R] Define pch and color based on two different columns
conditions look better as factors (their values are displayed in the strip label). groups should be a factor to get the uniqueness over panels. To use two factors together for groups, take their interaction. col and pch should be integers xyplot(mpg ~ wt | factor(cyl), data=mtcars, groups = factor(carb), col = mtcars$gear, pch = mtcars$carb ) xyplot(mpg ~ wt | factor(cyl), data=mtcars, groups = interaction(factor(carb), factor(gear)), col = mtcars$gear, pch = mtcars$carb ) On Wed, Apr 10, 2019 at 12:54 AM Peter Langfelder <peter.langfelder at gmail.com> wrote:> > Sorry for being late to the party, but has anyone suggested a minor > but important modification of the code from stack exchange? > > xyplot(mpg ~ wt | cyl, > panel = function(x, y, ..., groups, subscripts) { > pch <- mypch[factor(carb)[subscripts]] > col <- mycol[factor(gear)[subscripts]] > grp <- c(gear,carb) > panel.xyplot(x, y, pch = pch, col = col) > } > ) > > From the little I understand about what you're trying to do, this may > just do the trick. > > Peter > > On Tue, Apr 9, 2019 at 2:43 PM Matthew Snyder <msnyder424 at gmail.com> wrote: > > > > I am making a lattice plot and I would like to use the value in one column > > to define the pch and another column to define color of points.

I believe this is unnecessarily complicated. What the OP did not seem to get is that he had to specify the col's and pch's in the panel function that were actually used via appropriate subscripting. He just passed in the whole col and pch vector by default -- subscripting is not done unless specified.So the following does what I think he wants very simply: xyplot(mpg ~wt|cyl, data = mtcars, col = mtcars$gear, pch = mtcars$carb, panel = function(x,y, subscripts, col, pch,...) { panel.xyplot(x,y, col = col[subscripts], pch = pch[subscripts] ) }) Cheers, Bert Gunter "The trouble with having an open mind is that people keep coming along and sticking things into it." -- Opus (aka Berkeley Breathed in his "Bloom County" comic strip ) On Tue, Apr 9, 2019 at 9:53 PM Peter Langfelder <peter.langfelder at gmail.com> wrote:> Sorry for being late to the party, but has anyone suggested a minor > but important modification of the code from stack exchange? > > xyplot(mpg ~ wt | cyl, > panel = function(x, y, ..., groups, subscripts) { > pch <- mypch[factor(carb)[subscripts]] > col <- mycol[factor(gear)[subscripts]] > grp <- c(gear,carb) > panel.xyplot(x, y, pch = pch, col = col) > } > ) > > From the little I understand about what you're trying to do, this may > just do the trick. > > Peter > > On Tue, Apr 9, 2019 at 2:43 PM Matthew Snyder <msnyder424 at gmail.com> > wrote: > > > > I am making a lattice plot and I would like to use the value in one > column > > to define the pch and another column to define color of points.
