Thanks yo Tim and Jim for useful suggestions re: my query on circular plots.
Rethinking my goal, it appears Jim's suggestion of alternative linear
plots make more sense and likley more intuitive for reader.

Hi all...
I assume there are a host of GGplot2 users out there.
I have circular plot - polar plot code questions
I needed to create circular – polar plots of reproductive status for
bats. I found a great sample of how to do this here:

Hi all,
I am using reshape2 to reformat a data frame and all is great using:
Bats.melt <- melt(data = Bats)
Bats.cast <- dcast(data = Bats.melt, formula = Species ~ Location)
dput(Bats.cast,'C:/=Bat data working/Nica_new/Bats_niche.robj')
write.csv(Bat.cast,'C:/=Bat data working/Nica_new/test_
Hi all,
I am revisiting using reshape2 to aggregate critter (bats) occurrences
by time blocks and have the final output for each row sum a percentage
such that the row sums total 1 (100%).
Reshape2 library is loaded on start.
The old code I had stored in NotePad++ seems to no longer work as I
Hi all,
I am trying to set up logical function(s) to deal with two adjustments
to a blood glucose value.
I have been dinking around in Excel and assume this will be much easier
in R.
DF is date-time, BG value in mg/dL,test strip

H all,
I have relative abundance data from >100 sites. This is from acoustic
monitoring and usually the data is for 2-3 nights but in some cases my
be longer like months or years for each location..
The data output from my management data base is proved by species by
night for each location so
Hi all,
Diverging from my research based number crunching I am interested to see
what, if any R packages are out there that can access daily market
values of investment funds (e.g. using
http://quote.morningstar.com/fund/f.aspx?t=PDMIX) then store the data
value (i.e. NAV =$11.56 ) with date
Hi all,
I need to sub sample some large data sets.
The problem is using complete data samples for bats that are ± data per
1-minute time blocks using acoustic data collection and a method I
published some time back. Miller, B. W. 2001. A method for determining
relative activity of free flying
Hi Hadley et all,
I am struggling with reshape2 and melt works and melt_check
(filtered151) seems fine
My cast command was acast (filtered151, Time ~ Species ~ Number)
> melt_check (filtered151)
Using time, Species as id variables
$id
[1] "time""Species"
$measure
[1] "Number"
When I exec
I need to reformat long data into a wide format (matrix for another
program) but it does not seem straight forward.
Can not seem to get it to work since some data elements are strings.
Anyone have time to look at the issue?
Tnx

Hi all,
What is the best package to use to evaluate correlations between events
by time (species co-occurrence).
Chron?
I would like to determine fi there is any solid relationship between the
occurrence of critter A given critter B is present at a given time frame.
