Dear R help I have been trying to conduct a chi square test on two groups of variables to test whether there is any relationship between the two sets of variables chisq.test(oxygen, train) Pearson's Chi-squared test data: oxygen X-squared = 26.6576, df = 128, p-value = 1 > chisq.test(oxygen) Pearson's Chi-squared test data: oxygen X-squared = 26.6576, df = 128,

Dear R, I recently did a canonical correlation analysis on two subsets of data (location and weather). So I now have canonical scores for location and weather. but I'd now like to do a scatterplot matrix using the pairs statement. Is there a way to somehow join location.U and weather.V to become a new data set from which I could undertake a scatterplot matrix of the canonical variates?

can you recommend a good manual for R that starts with a data set and gives demonstrations on what can be done using R? I downloadedR Langauage definition and An introduction to R but haven't found them overly useful. I'd really like to be able to follow some tutorials using a dataset or many datasets. The datasets I have available on R are Data sets in package 'datasets':

can you tell me how to ask R to analyse a subset of data eg. supposing the data set consists of 9 columns and I only want R to analyse columns 1, 3 and 5 how would I command R to conduct eg. boxplots of those variables only? thanks brett Brett Stansfield Environmental Scientist - Water Quality Hawke's Bay Regional Council 102 Vautier Street Private Bag 6006 Napier Phone (06) 835-9200

Dear R I recently performed a cluster analysis. It produced the dendogram no problem but unfortunately the font size of the row.names were all cluttered due to their large size So I tried to change the font size using plclust(cluster.results, labels=iris$specie, cex=0.8) and R came back to me saying Error in plclust(cluster.results, labels = iris$specie, cex = 0.8) : unused argument(s)

Dear R I'm trying to do a correlation matrix for some variables I have. Unfortunately there are some NA entries for some of the variables I tried the following cor(sleep[c("logbw", "logbrw", "SlowSleep", "ParaSleep", "loglife", "loggest")]) but it told me Error in cor(sleep[c("logbw", "logbrw",

Dear R I recently did a scatterplot matrix using the following command pairs(sleep[c("SlowSleep", "ParaSleep", "logbw", "logbrw", "loglife", "loggest")],col=1+as.integer(ParaSleep > 5.5 | SlowSleep > 15.7)) this highlighted outlying points for some of the x,y plots that I needed to identify. Unfortunately this highlights all the x,y

Dear R Is there a way to apply row names as labels to a scatter plot matrix , I tried pairs(dogs, labels=row.names) Error in strwidth(labels, "user") : cannot coerce type closure to character vector I'm not sure what this means, however maybe you might know of a way to do this? brett stansfield

Dear R I recently asked for a cluster analysis Using * cluster.results <- hclust(iris.dist, method="complete") * but nothing happened i.e the previous scatterplot matrix still showed up whereas I was expecting a dendogram. Could it be that because I had used cutree before on the scatter plots that it somehow mucked it up. I tried detach then attach and commenced making the data

Dear R What does NaN mean? I recently did a correlation on a batch of data for some reason it didn't like one column cor(sleep,use="complete.obs") BodyWt BrainWt SlowSleep ParaSleep TotalSleep BodyWt 1.00000000 0.95584875 -0.3936373 -0.07488845 -0.3428373 BrainWt 0.95584875 1.00000000 -0.3867947 -0.07427740 -0.3370815 SlowSleep -0.39363729

Dear R Should I be concerned if the loadings to a Principle Component Analysis are as follows: Loadings: Comp.1 Comp.2 Comp.3 Comp.4 X100m -0.500 0.558 0.661 X200m -0.508 0.379 0.362 -0.683 X400m -0.505 -0.274 -0.794 -0.197 X800m -0.486 -0.686 0.486 0.239 Comp.1 Comp.2 Comp.3 Comp.4 SS loadings 1.00 1.00 1.00 1.00 Proportion Var 0.25 0.25 0.25

Dear R help I am having difficulty doing a biplot of the first two factors of a factor analysis. I presume it is because the values in factor 2 for Milk and NUTS are not displayed in the component loadings.

Dear R help Is there a way for R to ignore NA entries in a data set. I find I can do box plots for certain columns that have no NA entries but cannot do histograms or boxplots for the other columns that have NA entries Brett Stansfield

Hi I am working on a project of replication and need to know about few options related to web page replication in Red Hat linux/Apache enviornment. I am new in Linux. The scenario: I have two apache servers running on RH Linux-8 boxes. One of my web server is the master server(146.176.165.2) and I want to make the other one as a replica(146.176.165.1) of the master one. So, I need to replicate

I understand that most VoIP providers allow for 911 calling but that 911 service is not the same as that available to PSTN.

Hi, I'm trying to build a PDC and BDC to elimenate Windows NT on a network and have load balancing and fault tolerence for users. I've compiled samba 2.2.4 on two servers, working with openldap 2.0.23 with a master and a slave. Replication on LDAP servers works fine. I've set up a domain controller and wanted to set the other server as BDC in case the PDC goes down. Each time i put
