Ive got two columns in data_set that are strings
the first column is called character and has levels:

the second column is called abusive and has levels:

Thanks!!
this works perfectly
dat = data.frame(Aggressive = data_set$var1 , Behaviour=data_set$var2)
plot(table(dat))
...its better than a stacked boxplot as it gives also different width of
columns on the diagram...an extra layer of information.

Please help me persuade IT to install R on my computer!
All suggestions welcome.
Our IT department run scared when you mention software that they have no
working experience of.
I need to know the pros and cons of having R on corporate desktops.
Please no funny stuff, this is quite a serious

i just found the following list, i wondered if anybody could add to this as i
have to characterize a large data set and am new to R...the list below was
so helpfulcan you add to this???
Just to forestall confusion amongst those who would like to use one of
the functions called describe...
I have 20 columns of data, and in column 5 I have a value of 17600 but I
dont know which row this value is in (i have over 300,000 rows).
I'm trying to do 2 things:
1) I want to find out which row in column 5 has this number in it.
2) Then I want to print out that row with all the column
In excel a handy tool is the sort data by column ...i.e. i can highlight the
whole dataset and sort it according to a particular column...like sort the
data in a column in acending or decending order where all the other columns
change aswell.
I need to do this in R now but dont know how.
I want to do a non homogeneous poisson process model in R.
Any advice, or know of places where i can get some, ive googled it but
nothing came up relating to R.

this works perfectly...
new_data5 - new_data4[nchar(new_data4$date_abandoned) != 8, ]
...and i can now think of a few different ways to manipulate my data with
what ive learned from these tricks, thanks alot David!

The solution is much simpler (thanks Phil!)
new_data = data[!data$legal status %in% c(Private,Private

...works nicely.

I want to go through a column in data called
date_abandoneddata[date_abandoned]and remove all the rows that
have numbers greater than 1,010,000.
The dates are in the format 20091114 so i'm just going to treat them as
numbers for clean up purposes.
I know that i use subset but not sure
note, as i did this next...
dim(new_data5)
[1] 263 80
i now know that i have 263 dates in that column :)
I want to remove the 263 rows with dates and leave just the rows without a
date.
