save in for loop
Dear users,
My problem concerns save() within a for loop.
Here is my code:
for (i in 1:4) {
temp <- data.frame(a=(i+1):(i+10), b=LETTERS[(i+1):(i+10)])
filename <- paste("file", i, sep="")
assign(filename, temp)
save(filename, file=paste(filename, ".rda", sep=""))
}
As you can see, save() doesn't work as I would like: (1) the object

String search: Return "closest" match
Hi,
I have to match names where names can be recorded with errors or additions.
Now I am searching for a string search function which returns always the "closest" match. E.g. searching for "Washington" it should return only Washington but not Washington, D.C. But it also could be that the list contains only "Hamburg" but the record I am searching for is

Using smbclient and mount.cifs with SPN in Keytab
Hi,
for a static cifs mount (automount from fstab) I would like to use
kerberos with a SPN. The share is accessed from a http service, so I use
HTTP/www.samdom.example.com with the username
http-www.samdom.example.com. Unfortunately I can not get it to work.
The keytab is generated as described on [1].

Saving environment object
Hi,
When I create an environment object with new.env() and populate it with
values then how can I save it into an .RData file properly, so it can be
loaded later on in a new session?
Saving an environment object with save() or save.image() results in an error
message when loading again:
Error: protect(): protection stack overflow

Masked help page
Hi list,
not really a problem to solve but a strange unwanted behavior (at least I
do not like it):
I'm loading
library(multiv)
to use sammon.
Later I load
library(MASS)
which tells me that sammon is masked now, because
there is also a MASS version of sammon.
Since I believe that the MASS version is at least as good as the multiv
version, I would also use the MASS version, but

How to draw a tree?
Hi,
I have run rpart to construct a regression tree. Is there any simple
method to draw a nice picture of it, as it is usually done in books and
paper to visualize the tree?
Thank you,

Str info. Thanks for helping
It looks from str(SA) that Response IPS1 is a data.frame of class "anova", which probably cannot be coerced to vector.
Maybe you can use unlist() instead of as.vector()
Or something like
SA[["Response IPS1"]]["as.factor(WSD)",] ## to select the first row only, even maybe with unlist()
Without a better REPRODUCIBLE example, I cannot tell more (maybe some others

psychometric functions
Hi,
I want to fit some psychophysical data with cumulative gaussians. There is
quite a convenient toolbox for matlab called 'psignifit' (formerly known as
'psychofit'). It allows the lower bound of the sigmoid to vary slightly from
zero, aswell as the upper bound to vary from one. with these two free
parameters, the fitted function is less sensitive to noisy data and
outliers.

getMethod(s) and var.test
Hi,
How do I retrieve the var.test() function code? I had a similar problem once
before with another function but getMethods() solved the problem then. Now I
tried several combinations for var.test() without success.

Drivers supporting space_hard_limit
Hi,
In the XML documentation I found the element space_hard_limit for

number of items to replace is not a multiple of replacement length
Hey all,
I am writing a function in which I will have a matrix of 4 columns and a
variable amount of rows.
The first to columns will always contain be of the Character type, the third
and fourth columns
can be a variation of data types, usually characters and integers, but
sometimes lists or matrices.
At one point the code makes, for each row, a copy of that row, then it makes

user input
Dear users,
I have looked on different sources and found different functions to
prompt the user to provide input. However, I couldn't find one that does
exactly what I'm looking for.
select.list() and menu() are nice because a graphic window appears to
prompt the user. However, the user can only choose from a predefined
list of choices. readline() and scan() are more free in the

How to test if two C statistics are significantly different?
Hey all,
In order to test if a marker is a risk factor, I built two models (using cox
proportional hazard model). One model included this marker, and the other is
not.
Then, I use R package risksetROC to test how much predictive value did the
marker add to this model. I get two C statistics by analyzing the linear
predictors of the two models into this package.
