Hi. I'm trying to write an application to retrieve financial data
(specially bonds data) from FINRA. The web page is served dynamically
from an asp.net application:

I'd like to know if it's possible to fill dynamically

Hi Milan,
Take a look at the contr.Sum() and contr.Treatment() functions in the
car package.
Yeah, this is the kind of function I had in mind. Just that I think we
should have an equivalent in the base packages.

Hi Jose,
I think this is more of an r-help question so I'm going to forward
your question there: R-devel is really for the development of R
itself, not development with R.

Er, no!
R help is (mainly) for helping beginners. We usually
Hi,
Please consider the following :
x = c(1,3,NA,5)
y = c(2,NA,4,1)
min(x,y,na.rm=TRUE)# ok
[1] 1
max(x,y,na.rm=TRUE)# ok
[1] 5
sum(x,y,na.rm=TRUE)# ok
[1] 16
pmin(x,y,na.rm=TRUE) # ok
[1] 1 3 4 1
pmax(x,y,na.rm=TRUE) # ok
[1] 2 3 4 5
psum(x,y,na.rm=TRUE)
[1] 3 3 4 6

Why don't you make a matrix and use colSums or rowSums?
x = c(1,3,NA,5)
y = c(2,NA,4,1)
colSums(rbind(x, y), na.rm = TRUE)

Forest

Because that's inconsistent with pmin and pmax when two NAs are summed.
x = c(1,3,NA,NA,5)
y = c(2,NA,4,NA,1)
colSums(rbind(x, y), na.rm = TRUE)
[1] 3 3 4 0 6# actual
[1] 3 3 4 NA 6 # desired
and it would be less convenient/natural (and slower) than a psum which
would call
I don't know of an easy way to do this in R. I've been doing something
similar with python scripts called from R. If anyone knows how to do
this with just R, I would appreciate hearing too.

I think RHTMLForms works if you have a single form, but I have not been
able to see how to use it when you need to go through a sequence of
dynamically generated forms (like you can do with Python mechanize).

Is there a case to add psum? Or have I missed something.
If psum, then why not pdiff (-), pprod (*) and precip (/) ? And
similarly, what about equivalent functions for ^, %%, %/%, , and | ?

As far as getting to the data, I think the best way to do this sort of
thing would be if the site supports a SOAP or REST interface. When they
don't (yet) then one is faced with clicking through some pages. Python
or Java is one way to automate the process of clicking through the
pages.
A heads up for those using Rcpp and perhaps other packages related to
reference classes.
The changes in 61035 cause a problem for classes defined with a slot
using the return value of setRefClass(), notably for Rcpp. The name of
that class changed.
Rather than introduce
As of rev. 61035 in r-devel, setRefClass() now returns a generator function,
as setClass() has done since 2.15.0.
The convenient style is now:
mEdit - setRefClass(mEdit,..)
xx - mEdit(data = xMat)
instead of
xx - mEdit$new(data = xMat)
The returned object still has fields and
It appears that this problem only happens when R_LIBS is specified in
~/.Renviron. When it compiles 'relations', it's somehow not passing
along the correct lib paths.
This is the test code:
dir.create(test)
.libPaths(test)
install.packages(relations, type = source)
