| RE: How to use logical & and | in RGG [ Reply ] By: ilhami visne on 2009-02-28 22:21 | [forum:1296] |

Hello, The .rgg files are XML files and the & is a special character (http://en.wikipedia.org/wiki/List_of_XML_and_HTML_character_entity_references). The solution: if(a & b) And some other examples: - if(a < b) ==> if(a < b) - if(a > b) ==> if(a > b) Or assuming you have a big chunk of R code, then you can write them(actually anything) between <![CDATA[ and ]]> example: <![CDATA[ hh <- t(VADeaths)[, 5:1] mybarcol <- "gray20" mp <- barplot(hh, beside = TRUE, col = c("lightblue", "mistyrose", "lightcyan", "lavender"), legend = colnames(VADeaths), ylim= c(0,100), main = "Death Rates in Virginia", font.main = 4, sub = "Faked upper 2*sigma error bars", col.sub = mybarcol, cex.names = 1.5) ]]> i hope this helps, ilhami |
