Hello, I would like to retrieve data stored in MySQL database, so I installed RMySQL package. I can successfully connect with the my database using the following code > dvr<-dbDriver("MySQL") > con2<-dbConnect(dvr,group="exbardiv") > mysqlDescribeConnection(con2) <MySQLConnection:(972,0)> User: mmorag Host: localhost Dbname: exbardiv

Hi, I am trying to calculate a distance matrix on a binary data frame using dist.binary() {ade4}. This is the code I run and the error I get: > sjlc.dist <- dist.binary(as.data.frame(data), method=2) #D = (a+d) / (a+b+c+d) Error in if (any(df < 0)) stop("non negative value expected in df") : missing value where TRUE/FALSE needed I don't know if the problem are the

Dear Rhelp,   I did a daisy on 5 lifestyle variables, 3 of which were nominal and 2 were ordinal and assigned types “nominal” and “ordinal” for the variables, respectively.  I got an output indicating their types as “I” for interval(?). Doing it on the Rdata example “flower” gave the same types in the output as the types they were assigned to.  Why is this so? Below are the codes and outputs.  

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, 32, 33, 34, 35,

Hi all, I''ve been having trouble for a long time with backgroundrb processes that suddenly vanish without a trace. What happens is that at some point I discover that all the backgroundrb processes are suddenly gone. Nothing special is seen in any of the log files. This has happened intermittently for a long time, and I was hoping that upgrading to 1.0.4 would somehow help me out, but

To force guest access to a share, you need both guest ok = yes guest only = yes Otherwise it will try and authenticate you first before dropping you to guest. If this doesn't work, possibly you don't have a valid guest account set. If no account is set as the guest account (on the linux machine) it will use the user "nobody". > -Larry Engleman > The Burgiss Group >

Dear R-help, my aim is to fit a constrained 2 component gamma mixture using mix within package mixdist. The constraints being fixing both of the means and both of the sigmas. Thus the only unconstrained parameter I wish to fit is pi the proportions of the mixtures. This is the code I used: PP2Pars<-data.frame(c(0.23,0.77), c(9.174,29.54), c(9.983,12.369));

Something probably obivous but I don't see it. I needed to find the first 1 or two digits of some 5 and 6 digit numbers since they identified research sites while the rest of the number was the plot id. I converted the numbers to characters, got the first 1 or 2 characters as appropriate and went to add the new vector to the data.frame. For some reason R is insisting on turning the

Hi! I am trying to calculate a dissimilarity matrix using daisy. The matrix vectver is binary as i test with: > levels(as.factor(vectver)) [1] "0" "1" But the call to daisy gives me the following error message.: > dfl1 <- daisy(vectver, type = list(asymm = c(1:length(vectver[,1])))) Error in daisy(vectver, type = list(asymm = c(1:length(vectver[, 1])))) : at least

I put a bridging firewall together last winter (with some help) and have it= in production in front of a couple windows web and mail servers for going = on 6 months now. I used Fedora C1 with 2.4.22 kernel and 0.9.6 bridge-utils= . The bridge has solved a lot of security headaches. I use a modified start= up script written by David Whitmarsh that has worked really well. http://ww=

I'm resending this bug report with a new example. As seen below, cut.dendrogram gives an error message for some heights, but not for others and with some datasets adn not others. I can't see why. Last time I unwittingly sent my message with HTML formatting. This time I'm travelling and using an e-mail system that I am unfamiliar with. As far as I can see, I am not using HTML.

Hello, I'm a samba novice ;( Saw your "detailed" responses to another newbie questions so I thought I give you a shout :) Here is my setup: I've got 2 Linux boxes. One is running Ypserv and handles the authentication, the other is a 486 33mhz running ypbind(slave) and it is my printserver. The print server is also running 1.9.18 samba release as a daemon (smbd -D). It

salutations! i am doing some longitudinal modeling with sem and thought calculating some "simple variables" would make my model more readable. this is the smallest subset of my model that illustrates the resulting problem. i have 2 observed exogenous variables (c1, d2) and 4 observed endogenous variables (dc1, dd1, dc2, dd2). c1 is the observed state at time 1, dc1 is the change in c

Any idea why clusters five and six fall off the scale in the following? library(cluster) library(maptree) data(flower) dfl2<-daisy(flower,type=list(asymm=c(1,3),ordratio=7)) hdfl2<-hclust(dfl2) prune.dfl2<-prune.clust(hdfl2,k=6) plot(prune.dfl2) Of course the following will display all six clusters, but without a scale: draw.tree(prune.dfl2) Best wishes, Mikkel Mikkel Grum

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. -- View

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
