Hello,
I have a sample file:
chr22 100 150 125 21 0.145 +
chr22 200 300 212 13 0.05 +
chr22 345 365 351 12 0.09 +
chr22 500 750 510 15 0.10 +
chr22 500 750 642 9 0.02 +
chr22 800 900 850 10 0.05 +
where I need to generate a histogram from the data in column 6 (i.e.
0.145,
0.05, etc.). To make it easier to read, I would plot the data as
1-0.05=0.95
for all of the data in column 6.
That makes no sense to me, unless you want to pre-multiply all values
by 0.95.
What I would like to know is how to generate a histogram with the
data from
one file? Also, would I be able to generate one histogram from
multiple
files as well (with the same format)?
?hist
?histogram (# lattice
There are a ton of worked examples in the Archives. Learn to search.
Reasonable search terms once you get to Barons site with RSiteSearch
are (after setting the web interface to get r-help postings): "grouped
histogram"
For example, I have multiple files in the same format as the sample
file
above, and I would like to make one histogram for all column six
data in all
files.
Also there are a ton of worked examples in the archive dealing with
accessing multiple files.
Thank you,
