Delta column of TCGAanalyze_LevelTab function is misleading / buggy

[shucon]

Hello, the Delta column of the function is explained as the difference of gene expression between the two conditions multiplied logFC, but the code written shows the delta value as the gene expression of first condition multiplied logFC. I manually computed the values for delta and the former explanation seems to be true. Please clarify the same.
