Hi Listers, I am trying to reflect a PCA biplot in the x-axis (i.e. PC1) but am not having much success. In theory I believe all I need to do is multiply the site and species scores for the PC1 by -1, which would effectively flip the biplot. I am creating a blank plot using the plot command and accessing the results from a call to rda. I then use the calls to scores t...

Dear all, I'm writing my manuscript to publish after analysis my final data with ANOVA, ANCOVA, MANCOVA. In a section of my result, I did correlation of my data (2 categirical factors with 2 levels: Quantity & Quality; 2 dependent var: Irid.area & Casa.PC1, and 1 co-var: SL). But as some traits (here Irid.area) are significantly influenced by the covariate (standard length, SL), I need to use the partial correlation. I know how to calculate it with JMP, but as I used R to analyse all of my data (first time in my life) for this manuscript, can anyone...

Hi there! I'm super-happy because I've just finished my semi-auto configurator for Windows machines ^^ I've got a question: must all the users of a VPN share all together their hosts files? i.e. PC1 is linked to PC2 -> PC1 and PC2 must have both /hosts/PC1 and hosts/PC2 PC2 is linked to PC3 -> PC2 and PC3 must have both /hosts/PC2 and /hosts/PC3 Must PC3 have /hosts/PC1 and PC1 have /hosts/PC3? Thanks :D

I have two networked pcs. pc 1- RH8.0 which came with Samba-backend 1.0.8 and Samba 2.2.5 pc 2- XP Home I am able to access the shared folders from pc2 on pc1. However from pc2 I can not even see the ressources of pc1. In My Network Places/Entire Network/Microsoft Windows Network/"My Workgroup" I can see "pc1" but when I click on it I get an error message: \\"pc1" is not accessible. You might not have permission to use th...

...and then to LDAP with smbldap-useradd -a and access the server via Windows PCs. Everything appeared to be working correctly. My only problem is that I cannot seem to get a machine account added correctly. I've added the PC name to /etc/passwd etc. with "useradd -s /bin/false -g computers pc1$" and also run "smbldap-useradd -w pc1". When the computer attempts to join the domain it receives an "unable to join domain" error. It seems that "smbldap-useradd -w pc1" seems to add only a posix account to the LDAP backend ?: ----------- pc1$, Computers, domai...

...library. I am interested in this function because I would like to obtain "pseudo-R2" values (see http://tolstoy.newcastle.edu.au/R/help/02b/1011.html). Can anyone help me with the syntax? If I fit the model using the stats library, the code looks like this: model <- glm(x$trait ~ x$PC1 + I((x$PC1)^2) + I((x$PC1)^3), family = binomial) What would be the equivalent syntax for the lrm function?

...ct matter knowledge, I selected 4 important variables. Regarding the rest 9 variables, I tried to perform data reduction by principal component analysis (PCA). However, 8 of 9 variables were binary and only one continuous. I transformed the data by transcan of rms package and did PCA with princomp. PC1 explained only 20% of the variance. Still, I used the PC1 as a predictor of the logistic model and obtained some results. Then, I tried multiple correspondence analysis (MCA). The only one continuous variable was age. I transformed "age" variable to "age_Q" factor variable as t...
