In gene-patterns.Rmd, ensure factors for certain colData used in gene patterns

[menoldmt]

Problem:

Gene patterns gene cluster plots can get NA x-axis labels even though the x-axis is set to a valid column name here. This is because degPatterns expects factors when plotting time on the x-axis.

Proposed solution:



Use the colData column chosen in the configuration code above to set as factors in colData. Need to test for integer and float values e.g., "age" on the x-axis to see of those values would need to be set as factors as well or if they can get left as if for plotting.
