text format errors using xlsx package r

Question

I am importing an excel file (.xls) with read.xlsx() of the xlsx package in R, but I get the following changes in text formats:

i) three values in the original excel file (entries are in spanish): Alemán ; Portugués ; Búlgaro

ii) the three R data frame values after read.xlsx(): Alemán ; Portugués ; Búlgaro

How can I solve this? I´ve tried to control over colClasses but the only chances are numeric or character. The problem seems to be in the control of accents in the spanish language. I want to get the same values without coding for changes after the import. Is that possible? Thanks!
