Hello

I am trying to import the attached file Curva LIBOR to R. I am trying to use
the following commands and obtaining the following errors

> res <- read.xlsx("C:\\Users\\FELIPE
PARRA\\Documents\\Quantil\\Federacion\\Curva LIBOR.xlsx", 4)
Error en .jcall(rowCells[[ic]], "I", "getColumnIndex") :
  RcallMethod: invalid object parameter
> res <- read.xlsx("C:/Users/FELIPE PARRA/Documents/Quantil/Federacion/Curva
LIBOR.xlsx", 4)
Error en .jcall(rowCells[[ic]], "I", "getColumnIndex") :
  RcallMethod: invalid object parameter

> res <- read.xlsx(file, sheetName="LIBORSWAP")
Error en .jcall(rowCells[[ic]], "I", "getColumnIndex") :
  RcallMethod: invalid object parameter

does anybody knows what does this error means? Or do you have nay idea what
is a good way of importing big EXCEL files to R. Thank you

Felipe Parra
