What error?
Those are warning messages to do with your call to geom_bar. I've never
used geom_bar in that way, I'd create my summaries independently of
the graphing, so can't comment on how it should be used.
This simple example works fine for me:
```
library(ggplot2)
data(iris)
ggplot(iris) +
geom_point(aes(x = Sepal.Width, y = Sepal.Length)) +
facet_wrap(~ Species, nrow = 1) +
theme(strip.text = element_text(size = 10,face = 'bold'))
```

I am trying instead to increase the size with `theme(strip.text.x =

cases, even when using `strip.text`):

Hi Luigi,
# FROM HERE IT DOES NOT WORK
facet_grid(. ~ Species, scales="free_y") + # THE SCALE IS FIXED FOR ALL PANELS
I don't think you can force facet_grid to do this: the y scale will
always be fixed within a row (unless someone else tells you differently,
I may have misunderstood this) - this is to allow easy comparison and,
consequently, comprehension of the graphic as you scan across a row.
You can achieve what you want with:
facet_wrap(~ Species, nrow = 1, scales = "free_y")
but for the reason above, I'm not sure it's a good thing to do.
scale_colour_manual(values = c("palegreen4", "orangered3")) # THE
COLORS ARE AUTOMATIC
You're setting the colour manually - which relates to lines, not fill
and you have no colour aesthetic set, just a fill one.
Use scale_fill_manual(values = c("palegreen4", "orangered3")) instead.
I would also like to increase the size of the axis labels and the
title size of the panels.
What is the correct syntax?
See ?theme - you are interested in axis.title (maybe axis.title.x,
axis.title.y) and strip.text (the labels for the facets). See also
?element_text as in theme, you basically want to put something like
axis.title = element_text(...), replacing ... with the settings you
want.
For help specifically on ggplot2 and other tidyverse packages, I'd
recommend using https://community.rstudio.com in the future.
Best wishes,
Ron.
