calculating fold change from dataframe
Hey,
is there a code or a way to calculate the fold change?
all i could found is a calculations that includes only two variables, for example:
log2FC=Log2(B)-Log2(A)
but i have a data frame and i want to found the value , my data frame has more than two varables (i have more than one column for “healthy” and more than one column for “cancer”)
it looks for example like this:
| Gene | Healthy 1 | Health 2 | healty 3 | cancer 1 | cancer 2 |
|---|---|---|---|---|---|
| A | 3 | 4 | 4 | 5 | 6 |
| B | 4 | 5 | 4 | 2 | 1 |
| C | 0 | 8 | 7 | 2 | 3 |
i want to do it in order to make a volcano plot graph (if there is a way to avoid it, and add an graph based on other parametes i would be happy to hear from you as well)
thanks!
