strsplit(x, split= )
2013/7/3 Dan Murphy chiefmur...@gmail.com
I have a vector of strings that contain mathematical expressions. E.g.,
x - c(5 = 7, z = 1+2)
and I would like to decompose each expression into its left- and
right-hand-side components etc., output something like
5 = 7
z =
Dear useRs,
I am currently using the ctree function (package party) and am stuck at
the problem of getting a one-node tree (a tree with no splits consisting of
the root only) even if I maximally loosen all the stopping criteria
(mincriterion = 0, minbucket = 0, minsplit = 0).
In order to check
I suggest using vectorization :
find_row - function(m,v) { which(!(abs(rowSums(m - rep(v, each = nrow(m)))
)) 0) }
The function matroweqv mentioned above would give any row with the first
element equal to the first element in vector v.
The function find_row matches each row of the matrix as a
Dear R community,
I have recently discovered the package oblique.tree and I must admit that
it was a nice surprise for me,
since I have actually made my own version of a kind of a classifier which
uses the idea of oblique splits (splits by means of hyperplanes).
So I am now interested in
Dear R-society,
I know this is probably a question to LibSVM, but I have not found a
LibSVM mailing list, so I would be really grateful if someone from this
list helped me.
In the LibSVM documentation I have found a passage about dealing with
unbalanced sets, that says that in this case one
Use the `xlim` parameter of the `plot` function.
IFor example, if X1 and X2 are the variables that contain the values of your
x-axis,
do xlim1 - range(X1,X2),
than do plot(, xlim = xlim1,...)
Hope this helps.

Hello, dear R community.
The thing is that I am not in the least a developer, neither do I want to
create a package of my own.
But recently I have found a package LogicForest, which is in the base
written in Fortran I think. And well,
in its manual it is written that there are several parameters

Good afternoon,
I am actually concerned with this issue too. What if I run R at work and I
simply do not have the necessary access-rights in order to delete the .Rdata
file. Do I really have only 3 choices: ask the admin to delete it, live with
it always reloading the previous workspace, resave
I am very sorry. It's just that it's not my computer that the problem
occured on... It's at work. So I am going to see what distribution it was
when I get there. But I have no chance to know how R was installed... since
it wasn't me who installed it.
But could you please tell me , at least, where
be greatly appreciated.
Sincerely yours,
Yuliya Matveyeva.
