[R] Question about correlation

[SEB140004 Student]

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?

Moreover, isn't this data sets can be plot into network? If can, which
package should I use?

Thank you.

Best regards,
Kang Chin Yi
