Dear R Could you help here I'm trying to decifer what the principle component loadings are in an R output. Are they in any way related to eigen vectors or eigen values? Brett Stansfield

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...

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...

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...

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...

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...

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...

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...

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...

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...

Dear R When I go to do the biplot biplot(eurofood.fa$scores, eurofood$loadings) Error in 1:p : NA/NaN argument I think this is because the component loadings don't show values for some variables Loadings: Factor1 Factor2...

Dear R I am trying to plot some Principle component scores against the individual variables that made the first biplot. First I need to identify some points in the plot as follows running2 <- running[c("USA", "New Zealand", "Dominican Republic...

Dear R I recently created some variables in R as in I opened a data set and then produced log base 10 transformations on some of the variables. When I ask R to do a simple x, y plot it...

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...

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...

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...

I recently tried to make R highlight certain features in a scatterplot matrix pairs(sleep[c("SlowSleep", "ParaSleep", "logbrw", "loglife", "loggest", "logbw")], * col=1+as.integer(ParaSleep > 5.5)) this worked fine but when I wanted to add another condition...

Dear R I'm trying to plot the lda means onto a 2 D plot of discriminant scores. Preferably I'd like these to be in a larger font compared to the discriminant scores. I tried skull.mean.pred <- predict...
