I have a program that creates a Png file using Rgooglemap with an extent
(lonmin,lonmax,latmin,latmax)
I also have a contour plot of the same location, same extent, same sized
(height/width) png file.
I'm looking for a way to make the contour semi transparent and overlay it on
the google map (
I've read a number of examples on doing a multiple bar plot, but cant seem
to grasp
how they work or how to get my data into the proper form.
I have two variable holding the same factor
The variables were created using a cut command, The following simulates that
A - 1:100
B - 1:100
A[30:60] -
if your data for the rest of the file looks like this then read.fwf will
work.
depending which vars you want to pull)
widths= c(18,32,41)
E-CBIL-28-raw-cel-1435145228.cel1

Thanks for the pointer,
After looking at the many folders of R code I have I decided it was time to
start working in an IDE and also getting my stuff under version control (
for my own sanity)
I'll have a look at Geany.. for version control.. not so sure.

Ok I downloaded it and showed you how to get your data out. How to read it
into a raster brick,
how to plot the data, how to get the mean rainfall of every day.lots more
you can do.
there is a bad bit of data in the last time step.
check my blog.
In the future what you should do is write code
I'm doing some test processing of a cvs file that appears to use a different

I get the following warning:

My locale is US. Is this simply a matter of changing my locale to 'all;

I don't know what locale the string is
Thanks david.
Matevz, maybe I can help explain by doing a very simple and brute force
approach
as opposed to the way david did it. But you should learn his methods.
I will just do a subset of your problem and if you understand how it works
then you should

just merge the data.frames back together.
use merge or cbind()
cbind will be easier
DF1 - data.frame(x,y,z)
DF2 -data.frame(DF1$x) # copy a column
then you added columns to DF2
just put them back together

if you have, for example, the url of an ftp site you can merely do a
getURL() and the contents will be returned. That call will return data that
can be coerced into a data.frame that will look like a directory structure
listing the file names.
If you need code just ask, but
using RCurl
getFtpList - function(ftp){

Hmm,
RCurl might have something on this.
otherwise pull you can figure out their scheme and just construct the url
from scratch.
when you finish filling in the form, look at the url they construct. do it a

and you can just emulate that. I've done that in the past without problems.

I was talking with another guy on the list about this very topic.
A simple example would help.
first a sample C struct, and then how one would do the equivalent in R.
In the end i suppose one want to do a an 'array' of these structs, or list
of the structs.

The situation arises where I open a file to write a data.frame to it. with
write.table.
multiple lines are written to the file and the file is kept in Append=TRUE
mode.
If one sets the col.names to the names of the variables being written, you
have output
that looks like this...

Given a valid ftp address, is there a package that will allow me to get a
listing of the files/directory structure
on that site? RCurl looks to have this ability are there others?

so:

Any chance you may have already transformed m ?

Hi Gabor,
Not sure where to report this, but

I havent tested with other vignettes and cant imagine that is is specific to

The following dataframe will illustrate the problem
DF-data.frame(name=rep(1:5,each=2),x1=rep(A,10),x2=seq(10,19,by=1),x3=rep(NA,10),x4=seq(20,29,by=1))
DF$x3[5]-50
# we have a data frame. we are interested in the columns x2,x3,x4 which
contain sparse
# values and many NA.
DF

Thanks, the dataframe, is indeed clever at preserving its dimensions.
I'll try your solution with the real data
