Unexpected output in first iteration of for-loop
Dear r-helpers,
why do I get an output in the first iteration of the for-loop
which contains the string values of the input vector,
and how can I avoid that?
Here's the output (only line 1 is wrong)
latentVariable Indiv Group
1 rPlanning rIterat rTDD
2 rPlanning 0.79 0.84
3 rIterat 0.79 0.83
4 rTDD 0.9 0.96
5 rStandup 0.83 0.82
6 rRetros 0.9 0.95
7 rAccess 0.91 0.92
