Histogram in R with groups using Lattice/Mosaic?

Question

I am trying to make a histogram with two groups: one where (x<60 || x>100), and one where that condition is false.

Basically like this:

update 2023.08.03 - - - - - - -

This code is exactly what I want, but the color seems to be leaking between the lines:

histogram(~pulse, data = data, v = c(60,100), breaks = c(seq(from=40,to=140,by=20)), type = "percent", groups = ((pulse >= 100) | (pulse <= 60)))

histogram with vertical lines at 60 and 100, orange outside the lines and blue inside with some orange in the blue bars image

I tried:

• restarting R

• only one line/break image:

histogram(~pulse, data = data, v = 100,
    breaks = c(seq(from=40,to=140,by=20)),
    type = "percent", groups = (pulse >= 100))

• naming the constant where I want the line/group split image:

histogram(~pulse, data = data, v = num,
    breaks = c(40,60,80,num,120,140),
    type = "percent", groups = (pulse >= 100))

• different bin widths image:

histogram(~pulse, data = data, v = 100,
    breaks = c(seq(from=40,to=140,by=10)),
    type = "percent", groups = (pulse >= 100))

• not specifying the breaks image:

histogram(~pulse, data = data, v = 100,
    type = "percent", groups = (pulse >= 100))

If you have any ideas please let me know! I'm really hoping to stick to Lattice since I already have quite a few of these typed out ':)

end of update - - - - - - -

   

I tried this code but it gives me an error:

histogram(~pulse, data=data, type="percent", breaks=10, labels = TRUE, groups = (pulse > 60))

• Error using packet 1
• 'x' and 'units' must have length > 0

 

This code works, but it is only half of what I want:

set.seed(123)
var <- rnorm(700, 0, 0.25)
df <- as.data.frame(var)
num <- 0.5
histogram(~var, data = df, v = num, width = 0.2, type = "percent", groups = (var >= num))

My output: histogram with vertical line that splits it into blue and orange image

 

I have vague ideas of messing with panel or panel.superpose or maybe allow.multiple?

 

If this is relevant, here is my session info and more on the first histogram:
