addHeader Not Found

[jerive31]

Hi,

I copied and pasted your code in order to test it out on my instance of RStudio but continue to get a "could not find function "xlsx.addHeader"". Is there something wrong with the code or R? I'm fairly new to R so perhaps the answer is fairly simple, but thought I'd check in.

Al ejecutar xlsx.addHeader(wb, sheet, value="Header 1",level=1, color="black")

Aparece el siguiente mensaje: Error in .jnew("java.awt.Color", rgb[1], rgb[2], rgb[3]) : java.lang.NoClassDefFoundError: Could not initialize class java.awt.Color
