Residuals are stored as a numeric vector. The R software comes with a document "Introduction to R" that discusses basic math functions and logical operators that can create logical vectors:
abs( stdresiduals ) > 2.5 It also discusses indexing using logical vectors: stdresiduals[ abs( stdresiduals ) > 2.5 ] Note that in most cases it is worth going the extra step of making your example reproducible  because many problems arise from issues in the data or in code that you don't think is broken.  http://stackoverflow.com/questions/5963269/how-to-make-a-great-r-reproducible-example  http://adv-r.had.co.nz/Reproducibility.html  https://cran.r-project.org/web/packages/reprex/index.html (read the vignette) -- Sent from my phone.
