How to check if value is above threshold for each row, but the column to check changes each time

I have a df with 7 columns, the first 6 are log2FC values for gene expression, the 7th contains the name of the column with the highest log2FC value for each gene.

I'm trying to create a second df containing a column with either "yes" or "no", if the value in the column defined in df$max is above >=0.58.

The code I've tried creates a yes/no value for every gene in the df, rather than just the one gene per row, for the column specified in df$max, giving me a 5x5 df as a result. Instead I want it to be like this

ENSMUSG00000000001  no
ENSMUSG00000000028  no
ENSMUSG00000000031  yes
ENSMUSG00000000037  no
ENSMUSG00000000056  no

Any help appreciated :)
