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 <- read.csv(file.choose(), header=TRUE)
Enter file name: /home/userA/InsectSpraysCopy.csv
I either don't understand what you're doing, or you seem
very confused.
R comes with many sample data sets for you to use.
You can see a list of them using the ?data function.
Calling data with an argument loads that dataset.
So, when you type:
> data(InsectSprays)
that data object is now available in R, see
> objects()
You can look at it simply by printing it:
> InsectSprays
If for some reason it makes sense to do it this way for your
use case, then that's fine, I just want to make sure you understand
that you don't have to if accessing built-in datasets is all you want.
### Look at the data
test01
X count spray
1 1 10 A
2 2 7 A
3 3 20 A
<snip>
### Create a side-by-side boxplot of the data
boxplot(test01$DO ~ test01$Stream)
Error in model.frame.default(formula = test01$DO ~ test01$Stream) :
invalid type (NULL) for variable 'test01$DO'
Why do you think test01 has an element called "D0" or "Stream"?? The
column names when you print the data tell you otherwise!
