Hi,
Firstly, apologies as I have posted this on community.rstudio.com too.
I want to optimise a Box-Cox transformation on columns of a matrix (ie, a
unique lambda for each column). So I wrote a function that includes the call to
MASS::boxcox in order that it can be applied to each column
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) +
2 matches
