Question about correlation
Hi Chin Yi, If you are trying to correlate "Health" with "Disease", i.e. cydf<-read.table(text="OTU ID Health Disease Bacterial 1 0.29 0.34 Bacterial 2 0.25 0.07 Bacterial 3 0.06 0.06 Bacterial 4 0.07 0.09 Bacterial 5 0.02 0.05", header=TRUE) print(cor(cydf$Health,cydf$Disease)) [1] 0.7103517 If you are getting that error, it probably means that

Question about correlation
I think that Goran is right, I didn't take "cor(data)" literally.

vegan -varpart is bigger than 100% in total?
I am trying to find the percentage of the parameters explaining the bacterial community composition. I have one data matrix with relative abundance of OTUs and one with environmental parameters. I used varpart in vegan package but the values in the venn diagram is bigger than 100% in total.How is it possible? What might be the reason? Thank you library(vegan) gotud <-

Hello! I am eager to learn if I only have a data about the relationship between otu and sample, could I use the function capscale, and final make a point plot that x-axis is CAP1 and y-axis is CAP2? Besides, what function could I use to make the different rarefaction curve with different color in the a plot in R? Appreciate very much.

plot significant spearman correlation
Hello, I calculate the correlation between two matrices cor(x,y, method="spearman") and I am wondering if it possible to see only the significant correlations. I can do that for single OTUs with cor.test() command but I would like to have an output for whole matrix. Besides,I would like to plot the relative abundance of each OTU, against the number of significant pair-wise correlations

NMDS plot and Adonis (PerMANOVA) of community composition with presence absence and relative intensity
Hi! Thanks for providing great help in R-related statistics. Now, however I''m stuck. I''m not a statistics person but I was recommended to use R to perform a nmds plot and PerMANOVA of my dataset. Sample(treatment) in the columns and species (OTU) in the rows. I have 4 treatments (Ambient Temperature, Ambient temperature+Low pH, High temperature, High temperature+low pH), and I

gplot heatmaps: clustering according to rowsidecolors + key.xtickfun
Hi there, I have two questions about heatmap.2 in gplot. My input is a simple square matrix with numeric values between 75 and 100 (it is a similarity matrix based on bacterial DNA sequences). 1. I can sort my input matrix into categories with rowsidecolors (in this case, very conveniently by bacterial taxa). I do a clustering and reordering of my matrix by Rowv=TRUE (and

How can one use GRUFF with locomotive ( I guess there is a wider question here, also)
Hi: I love Locomotive and use it exclusively for my rails projects. I''d like to install GRUFF and give it a try (a graph image creation package). I know I can do sudo gem install gruff from the command line for normal ruby and rails. How do I make gems available to Locomotive? bruce

Confidence Intervals on Standard Curve
Hi, I wonder if anyone could advise me with this: I''ve been trying to make a standard curve in R with lm() of some standards from a spectrophotometer, so as I can express the curve as a formula, and so obtain values from my treated samples by plugging in readings into the formula, instead of trying to judge things by eye, with a curve drawn by hand. It is a curve and so I used the

Under-dispersion - a stats question?
Hello all: I frequently have glm models in which the residual variance is much lower than the residual degrees of freedom (e.g. Res.Dev=30.5, Res.DF = 82). Is it appropriate for me to use a quasipoisson error distribution and test it with an F distribution? It seems to me that I could stand to gain a much-reduced standard error if I let the procedure estimate my dispersion factor (which

Setting up Ruby + RubyOnRails on the new intel mac (any feedback?)
Hi I''m about to attempt to setup RoR on an iMac powered by an Intel core duo. Before I start, is there anyone who would have some feedback about a similar setup (and likely, the caveats hidden down there) ? thanks!
