[R] Display all element names neatly in a Venn Diagram
Hello, I want to create a Venn diagram that displays all the elements of the sets and overlap regions. The closest tool I've found for this is in Vennerable, described here: http://stackoverflow.com/questions/7029987/r-how-to-display-elements-instead-of-just-counts-within-each-circle-of-a-venn However, this does not actually fit the elements within the regions but instead makes a single long name for that region from the element names. At the very least, I would like to reformat the name onto multiple lines. Any suggestions? -david -- View this message in context: http://r.789695.n4.nabble.com/Display-all-element-names-neatly-in-a-Venn-Diagram-tp4676631.html Sent from the R help mailing list archive at Nabble.com. __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
[R] crosstabs and histograms with flexible binning of dates
Hi,
First, thank you to Duncan Mackay for getting me started processing dates
with R. Unfortunately, I need to do a little more than I initially expected.
I have 5K lines of data that look like this:
ID AREA DATE
0001 Center 2010-10-15
0002 Center 2010-01-02
0003 NorthWest 2010-02-05
0004 SouthWest 2010-05-11
I would like to create a script to create crosstabs like the one below, but
that (1) could be used to easily create small multiples with lattice or
ggplot2 and (2) provides flexible binning options, such as monthly from a
specific day. Should I manually create the crosstab or can I use a histogram
function to generate it on the way to generating a graphic?
AREA 1/2010-3/2010 4/2010-6/20107/2010-9/2010 10/2010-12/2010
Center 1 0 0 1
NorthWest 1 0 0 0
SouthWest 0 1 0 0
Below is my code to handle the arbitrary bins, but I'm guessing there are
useful libraries and more elegant approaches. Any pointers would be
appreciated.
import(foreign)
# LOAD FILE
#parcels=read.dbf() #depending on source file
parcels=read.delim(~/Projects/GIS_DATA/Parcels_NSP_BlockGroup.txt)
attach(parcels)
# DEFINE BINNING
basedate=as.Date(2011/05/11)
currentdate=basedate
interval=3 #width of interval in months. 3 = quarterly
num_intervals=5 #how many intervals to include after basedate
for (i in c(1:num_intervals)) {
startdate=currentdate
enddate=seq(startdate,by=month,length=interval)[interval] #create a
sequence of months of length interval and take last one.
# crosstab construction of single column here
# add column to final dataframe
currentdate=enddate
}
Thank you,
-david

[R] trouble with small multiples on a date variable
Hello, I am loading a DBF file into R via JGR and am having trouble creating small multiple histograms on a date variable. Hist() handles the variable correctly. But I've been unable to work with lattice or ggplot2 despite trying format() and as.POSIXct(). Dates are in the format 2010-05-15 and the grouping variable is categorical. I'd appreciate it if someone would provide an example.
