I have not used the psych package, so not sure about the differences in the function or what type of object it returns. xtable has support for: > methods(xtable) [1] xtable.anova* xtable.aov* [3] xtable.aovlist* xtable.coxph* [5] xtable.data.frame* xtable.glm* [7] xtable.lm* xtable.matrix* [9] xtable.prcomp* xtable.summary.aov* [11] xtable.summary.aovlist* xtable.summary.glm* [13] xtable.summary.lm* xtable.summary.prcomp* [15] xtable.table* xtable.ts* [17] xtable.zoo* So it would seem that there is a method for 'prcomp' class objects, as opposed to 'princomp', albeit, there are similarities. Typically, if there is not a built-in method for a given class, you would need to create an object of a class that is supported, containing the results that you want to output. So that could perhaps be either a matrix or a data frame, which ever is more suitable for your case.
