Depends on what graphs were talking about: A Side-by-side boxplot containing
fx 4 boxplots can be generated by a single plot() command. However often you
use a primary command that activivates
the plot window and plots one graph, then afterwards you use s
orial with demo. Otherwise it won't be easy for a
beginning remembering all commands and steps on manual.

If you're trying to follow the youtube video you have a typing mistake here:
InsectSprays.aov <-(test01$count ~ test01$spray)
I think this should be:

If you're trying to follow the youtube video you have a typing mistake here:
InsectSprays.aov <-(test01$count ~ test01$spray)
I think this should be:
InsectSprays.aov <-aov(test01$count ~ test01$spray)
youre missing the functioncall "aov" on the right hand side of the
assignment operator '<-'

Performed following steps on R:-
### to access to the object
data(InsectSprays)
### create a .csv file
write.csv(InsectSprays, "InsectSpraysCopy.csv")
On another terminal
$ sudo updatedb
$ locate InsectSpraysCopy.csv
/home/userA/InsectSpraysCopy.csv
### Read in some data
test01 <- re
rocedure
TukeyHSD(dotest01.aov)
Any advice? TIA

Hi folks,
File to be used is on;

I can't figure out where to insert it on following command;
test01 <- read.csv(fil.choose(), header=TRUE)
Don't think that would work, even if you did spell file.choose()
correctly.
