[R] Way to Plot Multiple Variables and Change Color
The colors can be specified with the standard lattice "col=" argument.
likert(t(BB), ReferenceZero=0, horizontal=FALSE,
col=RColorBrewer::brewer.pal(4, "Blues"))
Most other customizations you might need are also possible. Many examples
are in the examples section of ?likert and in the demo.

[R] Antwort: Re: Way to Plot Multiple Variables and Change Color
Hi Georg,
you were on the right path - it is all about scale_fill*
The 'problem' as you've discovered is that value is continuous, but
applying scale_fill_manual or others (except scale_fill_gradient) expects
discrete values.
The solution is simply to set the fill with that by using factor():
ggplot(
d_result,
aes(variable, y = n, fill = factor(value))) +
geom_bar(stat = "identity") +
scale_fill_manual(values = RColorBrewer::brewer.pal(4, "Blues"))
or:
ggplot(
d_result,
aes(variable, y = n, fill = factor(value))) +
geom_bar(stat = "identity") +
scale_fill_manual(values = c("red","blue",
"green", "purple"))
When using colorBrewer (which I highly recommend), I use scale_*_brewer
rather than setting the colour manually:
ggplot(
d_result,
aes(variable, y = n, fill = factor(value))) +
geom_bar(stat = "identity") +
scale_fill_brewer(palette = "Blues ")
Best,
Ulrik

I tried to change the order of the items on the y-axis, e.g. Item 8
should be last and Item 1 first. I tried to reverse the order of the items
within ggplot using rev() and relevel(). But neither of them worked. Is
there a way to do it?
I also tried to adjust the color palette for the legend, e.g. 1 = very
satisfied is green, 6 = very dissatified is red instead of vice versa as
it is now. The result should ensure the item naming for 1 = satisfied and
6 = unsatifies cause this is the way it was asked in the questionnaire.
Thus my question is:
1. How can I change the order of the sequence for the y-axis?
2. How can I adjust the color palette of the legend that it matches the
correct items?
Can you give me a hint which functions I could use to do it?
Kind regards
Georg

Change Color
Hi Georg,
you were on the right path - it is all about scale_fill*
The 'problem' as you've discovered is that value is continuous, but
applying scale_fill_manual or others (except scale_fill_gradient) expects
discrete values.
The solution is simply to set the fill with that by using factor():
ggplot(
d_result,
aes(variable, y = n, fill = factor(value))) +
geom_bar(stat = "identity") +
scale_fill_manual(values = RColorBrewer::brewer.pal(4, "Blues"))
or:
ggplot(
d_result,
aes(variable, y = n, fill = factor(value))) +
geom_bar(stat = "identity") +
scale_fill_manual(values = c("red","blue",
"green", "purple"))
When using colorBrewer (which I highly recommend), I use scale_*_brewer
rather than setting the colour manually:
ggplot(
d_result,
aes(variable, y = n, fill = factor(value))) +
geom_bar(stat = "identity") +
scale_fill_brewer(palette = "Blues ")
Best,
Ulrik

Hi Richard,
many thanks for your reply.
Your solution is not exactly what I was looking for. I would like to know
how I can change the colors of the stacked bars in my plot and not use the
default values. How can this be done?
Kind regards
Georg

I think you are looking for the likert function in the HH
package.>From ?likert
Diverging stacked barcharts for Likert, semantic differential, rating
scale data, and population pyramids.
This will get you started. Much more fine control is available. See
the examples and demo.
## install.packages("HH") ## if not yet on your system.
library(HH)
AA <- dfr[,-9]
labels <- sort(unique(as.vector(data.matrix(AA))))
result.template <- integer(length(labels))
names(result.template) <- labels
BB <- apply(AA, 2, function(x, result=result.template) {
tx <- table(x)
result[names(tx)] <- tx
result
}
)
BB
likert(t(BB), ReferenceZero=0, horizontal=FALSE)
