Dear R Can you tell me how to change the working directory of R It's just that I have some text files that I wish to save separately from the R filing structure eg. into C:/my documents and need to change the working directory of R so that it reads these files . This means if I ever upgrade the current version of R nothing will be effected. brett Brett Stansfield Environmental Scientist -

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,

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 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

Hi All I am using the following command to update data from one server to another one. But it is returning back with error. Without SSH: [root@pc165017 var]# rsync -ae /var/www pc165002.napier.ac.uk:/var/www Failed to exec /var/www : Permission denied rsync error: error in IPC code (code 14) at util.c(162) rsync: connection unexpectedly closed (0 bytes read so far) rsync error: error in rsync

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 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. Loadings: Factor1 Factor2 RedMeat 0.561 -0.112 WhiteMeat 0.593 -0.432 Eggs 0.839 -0.195 Milk 0.679 Fish 0.300 0.951 Cereals -0.902 -0.267

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

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

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

type ?cor and read the help file In particular read it till you find the entry that tells you how to deal with missing observations. You need to do this because as you get more competent you will undoubdtedly come across other issues, so learning the format of the help and realising why you need to check the Arguments section will reduce your frustration in the future. You also need to read the

Hi, Where can I find information ( freely available on the Internet , and also books or other sources ) on how having sampling weights changes the calculation of the standard error (of means and proportions)? How good is R for this type of procedure? And SAS? thanks Robert [[alternative HTML version deleted]]

I've been asked about "Canonical Variance Analysis" (CVA). I don't see any reference to it searching the R site. Does it go by other names? Genstat describes it thus: Canonical variates analysis operates on a within-group sums of squares and products matrix, calculated from a set of variates and factor that specifies the grouping of units. It finds linear combinations of the
