Wine & Games problem
hi!
i run quake2(an ooooold game) with wine, and it works perfectly with
opengl and it seems to works ok, but, when i try to write something in the
game-console i can't, i see the game but i can't use my keyboard on
it. The same thing happen to me with jedi outcast II, i see the game but i
can't use my keyboard.. the mouse works fine, but not the keyboard.
thanks for your help.

weighting variables using Gower with DAISY
Hello,
I am running DAISY in R and using the GOWER metric since I am working with
mixed variables. I am wondering if there is a way to weight the different
variables. I see that there is a weight value for Gower but do not know if
this is how to weight the diffrent variables with different weighting
values. Please advise if there is a way to weight the different variables.
Thank you.

want to count 2 NULLS as disimilar with DIANA/DAISY/GOWER
I am using DIANA/DAISY/GOWER. Some of my categorical data include NULLS.
When assessing disimilarity, these NULLS are considered similar. I do not
want these NULLS to contribute towards similarity. Instead is there a way
for these NULLS to each be considered different so as to contribute to
disimiliarity and not simillarity? Also, I do not want to change these NULLS
in the data as I need them for

more on the daisy function
Dear R-helpers,
First of all, a happy new year to everyone!
I succesfully used the daisy function (from package cluster) to find which two
rows from a dataframe differ by only one value, and I now want to come up with
a simpler way to find _which_ value makes the difference between any such
pair of two rows.
Consider a very small example (the actual data counts thousands of rows):

daisy function in cluster- coerced NAs
I am currently using the function daisy in package cluster to create a
dissimilarity matrix because my multivariate dataset contain missing
data and variables of various types including factors, symmetric and
asymmetric binary and quantitative. This is a step prior to using pco
within ecodist.
There is a warning which comes twice

daisy(): space allocation issue
Hi,
I'm trying to apply the function daisy() to a data.frame 10000x10 but I have
not enough space (error message: cannot allocate vector of length
1476173280).
I didn't imagine I was not able to work with a matrix of just 10000
observations... I have setted in Rgui --max-mem-size=2G (I'm not able to set
more space..)
How can I solve this issue? Separating observations depending on

Correct use of the cluster::daisy function
Hi,
I have two groups, and I want to find the dissimiarity between the members
of the two groups. Since I have mixed level variables on the members, I opt
for the daisy function in the cluster package.
Let's pretend that the following represent my groups:
x <- data.frame(sex=factor(c(1,0,0,1,0,1),
levels=0:1,
labels=c('Male','Female'),
ordered=FALSE),

Specify ID variable in daisy{cluster}
Hi All - I am using the daisy function from the cluster library to create a
dissimilarity matrix. I'm going to use that matrix to run a cluster
analysis. My participants are identified with the variable, hhid. However,
when I try to keep hhid in the dataset that I use to create the
dissimilarity matrix, daisy uses it to create the matrix rather than
ignoring it as an ID variable. I need to

error using daisy() in library(cluster). Bug?
Hi,
I'm using the cluster library to examine multivariate data.
The data come from a connection to a postgres database, and I did a short R
script to do the analisys. With the cluster version included in R1.8.0, daisy
worked well for my data, but now, when I call daisy, I obtain the following
messages:

type in daisy
Hi,
I'm a PhD student and I want to use the function 'daisy' from the
package 'cluster' to compute dissimilarities.
My variables are of mixed types so I use the argument 'stand' in daisy
to define the type of my variables.
I have the following error message :
Warning message:
binary variable(s) 13, 16, 17, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31,

Why daisy() in cluster library failed to exclude NA when computing dissimilarity
Hi,
According to daisy function from cluster documentation, it can compute
dissimilarity when NA (missing) value(s) is present.
http://stat.ethz.ch/R-manual/R-devel/library/cluster/html/daisy.html
But why when I tried this code
library(cluster)
x <- c(1.115,NA,NA,0.971,NA)
y <- c(NA,1.006,NA,NA,0.645)
df <- as.data.frame(rbind(x,y))
daisy(df,metric="gower")
It gave this
