You're not giving people much to work with. I googled the error, and it seems
to come from the call to optim and has likely to do with bad starting

Basically you'd need a loop to create the sets, and a way to write them into a

If indices are important:
Actually this might be shorter for working with indices:
v1[names(v1)%in%names(v2)]+v2[names(v2)%in%names(v1)]

Hi
Your description is quite long but almost uninformative about what you
really want.
You do not say which values you want to sum
?merge and ?unique might help
however: why is calee_id a floating point number? Ids are usually stuff thats
close to a factor, integers, strings and the like, you know stuff that has a
value that isn't dependant on precision. Floating points might just complicate
things..

should work then. You do know which 40 of your 49 banks you want
I assume result means the invalid variable.
works with sample data frame i made, so please provide an example of cdb_frame.
You can use dput(cdb_frame) for that, or dput(head(cdb_frame)) if you have a
lot of data.
For example it could be that $Publication is a string, not numeric.

Hi!
The kernlab function kpca() mentions that new observations can be transformed
by using predict. Theres also an example in the documentation, but as you can
see i am getting an error there (As i do with my own data). I'm not sure whats
wrong at the moment. I haven't any predict functions

Now i'm scratching my head as well, thought it might have to do with scaling at
first, so i turned it off, and also tried scaling the data for the plot
instead, but to no avail, it just switches the color, but doesn't show the
correct contours.
And it is at least predicting the stuff right, so

For example will let you view a bit of that separating plane. I'm not getting
creative on how to find the best values there though..

You could have googled R solve equation, and would have easily reached
http://r.789695.n4.nabble.com/R-solve-equation-td882585.html
and would have in there found something like this:
z - matrix(c(-8.313,-1,1), ncol=1)
polyroot(z)
[1] 3.42626+0i -2.42626+0i
p-polyroot(z)
p^2-p
[1] 8.313+0i
example
but a wild guess: if your class information is numeric the default is to do
eps-regression, not classification. Use factors or specify the type you want to
use.
?svm
might help there.

You mean executing the function for all combinations of values?
For example, if you have a-b-c-1:2
you would get back the values of
myfunc(1,1,1)
myfunc(1,1,2)
myfunc(1,2,1)
myfunc(1,2,2)
myfunc(2,1,1)
myfunc(2,1,2)
myfunc(2,2,1)
myfunc(2,2,2)
?

When i make Boxplots with a lot of boxes, the names of them get only written
down every second column.
Since they aren't in any way ordered, you don't see anymore to what they belong.
example:
l-rep(list(1:5),20); boxplot(l,names=sample(20,1:20))
Is there a way to show them all, or do i have
Copied the wrong lines, sry
l-rep(list(1:5),20); boxplot(l,names=sample(1:20,20))
of course.
thanks for the answer

I think you need to elaborate a bit. At least I get no idea of what you want
from that one sentence.

Try again please,
so you have a table/dataframe or some such with 4(?) columns:
module_name, class_name, function_name and function_description
I guess under the second line shall be an example of data in the table, but i
cannot see what belongs to what column.
If you have an example table
Oh, i think i get it now, you're talking about formatting a table in a
