Correlation values from scatter plot matrix

[sambo988]

Hi there!

I'm using bigPint for some RNAseq analysis (3 groups, 9-11 samples per group). I generated scatter plot matrices comparing conditions but was wondering if there was anyway to extract just the correlation values for each comparison?

Thank you!

Hello Danielle:

Sorry for my (very) slow reply.

If you are looking to simply extract correlation values, you can likely do this with the cor() function in base R. As a MWE using some of the toy data from bigPint:

library(bigPint)
library(dplyr)

data("soybean_cn_sub")
data = soybean_cn_sub %>% select(ID, starts_with("S1"), starts_with("S3"))
cor(data[,2:7])

This should return a matrix of correlation values for the six variables of the data.

Is this what you were looking for?
