# [R] introduce axis break lattice plot multipanel

```Dear all,
I am plotting some data using lattice's barchart. One of the counts I
am plotting has a very large value with respect to the other variables
and I would like to introduce a break in the axis to compensate for
this 'anomaly' and give more breath to the other bars. In this example
the high count is for the variable 'b' and I would like to introduce a
break of 50-100 in the x axis.
I have seen from the internet that the common approach is to stack
together two figures but in my case I am using a multipanel plot and I
think this way won't work for my plot.
Is there a simple way to introduce a break in the axis of a multipanel
lattice plot?
Thank you
L

the example:
>>>
A <- c('a',    'b',    'c',    'd',    'a',    'b',    'c',    'd',
'b',    'c',    'd',    'b',    'c',    'd')
B <- c(1,    1,    1,    1,    1,    1,    1,    1,    1,    1,    1,
1,    1,    1)
C <- c(0,    0,    0,    0,    1,    1,    1,    1,    0,    0,    0,
1,    1,    1)
D <- c(4,    120,    7,    23,    4,    24,    3,    12,    7,    1,
1,    5,    0,    0)
E <- c(0,    0,    0,    0,    0,    0,    0,    0,    1,    1,    1,
1,    1,    1)
DF <- data.frame(A, B, C, D, E, stringsAsFactors = FALSE)
library(lattice)
barchart(
A ~ D|E,
DF,
groups = C,
stack = TRUE,
main = "Comparison of test results",
xlab = "Count",
col = c("yellow", "orange"),
par.settings = list(
strip.background = list(col="light grey"),
superpose.polygon=list(col= c("yellow", "orange"))
),
scales = list(
alternating = FALSE
),
key = list(
space="top",
columns=2,
text=list(c("Single infections", "Multiple infections"), col="black"),
rectangles=list(col=c("yellow", "orange"))
),
)
