Christofer, I do not really use the xlsx package, so this may not be the 'best' approach. And based on your spreadsheet, and the code that you supplied, I am not sure what you really intended. But here is some sample code that will update cells in your spreadsheet without changing the formatt

Re: [R] Testing significance of individual regression slopes

You can't if I understand correctly: there is no individual subject regression coefficient, only a variance component for a random subject intercept. Do you mean that you want to "test" whether that component is nonzero ?(It is, of course). If so, IIRC, lmer eschews such tests for technical reason
