Does anyone know how to use R for statistics

[theholygideons]

What the fuarkk, It won't plot a boxplot for some reason. This is annoying..

[j_menz]

In what program?

[senanserat]

Are we talking about R= |U|-> A U B ?

[theholygideons]

this program.. R x64 3.0.2
it's free software that my uni course requires me to use..

[theholygideons]

it thinks i have 2 quantitative variables, when i have 1 quantitative and 1 categorical. What the fuark.

[senanserat]

Though we were talking 'bout dem math formulas...

[j_menz]

There's always the manuals.....

[theholygideons]

for some reason it isn't reading the tab delimited file correct, what the ***
I hate technology, screw this, why don't we all just revert back to using pen and paper

[j_menz]

Have you tried changing it to a comma delimited one?

[theholygideons]

what's the difference? o-o

[theholygideons]

ok i give up. not worth the effort, i'll just ask a friend

[j_menz]

what's the difference? o-o

The character used to delineate fields. Comma separated is more common, so may be handled better (or indeed be what it is expecting).

R, if you are meaning the correlation coefficient between two variables which it seems as though you are, is only usable for two quantitative variables.  Further, to be reliable, both of those variables must be normally distributed, or transformed in such a way that they are normally distributed.

There are correlation statistics which can be use for categorical variables, but R isn't one of them.

i'm talking about R as the program, mate.
i thought correlation coefficient was lower case r anyway.
thanks for trying to help anyhow.

If you have one quantitative variable x you need to change to a category variable try

x <- factor(x)

Then try your boxplot again.

Edit:  Oops.  The original post had category(x) which isn't a command.
