Greeting. Dear Mr/Mrs/Miss, I want to create a network by using R but I only have a table that contain OTU ID and the abundance value of two samples ONLY. Isn't possible? If can, which package can be used? Greatly appreciated to any suggestions and helps. Thank you. Best regards, Kang Chin Yi [[alternative HTML version deleted]]

...th" or "Disease" or perhaps both have been read in as a factor. To test this: is.factor(cydf$Health) [1] FALSE > is.factor(cydf$Disease) [1] FALSE If either of these returns TRUE, that is almost certainly the problem.

Greeting. Dear Mr/Mrs/Miss, 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 Above show the first 6 data sets, may I ask that the reason of R show the error like "Error in cor(data) : 'x' must be numeric" ? And how to solve it? Besides, isn't this data can conduct correlation matrix?
