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 either "Health" or &quo...

Ask help
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 to other OTUs. However, I do not know how to introduce p <.05 parameter in the script. Thank yo...

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 have 16 different species (OTUs). Firstly I want to make a nmds plot and see how different the treatments are. Meaning how the species covaries with the environment...

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 <- decostand(gotu,"hell") G.var <- varpart(gotud,~Depth,~CH4_oxidati...
