What it does
This tool generates a Principal component analysis (PCA) for a given table using a combination of ggplot2 and ggfortify.
Example
WARNING: Be carefull when selecting row names in the second option because the grouping elements do not update automaticly before executing the script. This means that columns have to be chosen as if the row name column was already be removed.
Example for row names in table
| name | control 1 | control 2 | treatment 1 | treatment 2 |
|---|---|---|---|---|
| gene 1 | 10 | 12 | 3455 | 232 |
| gene 2 | 20 | 2 | 345 | 334 |
| gene 3 | 200 | 210 | 20 | 2 |
| 1 | 2 | 3 | 4 | 5 |
The new index after reading the table will be:
| name | control 1 | control 2 | treatment 1 | treatment 2 |
|---|---|---|---|---|
| 1 | 2 | 3 | 4 |
