Hi, a developer asked me something (we were talking about a issue in R highlighting) Here it is: "P.S.: Shouldn't constants like TRUE, FALSE, Inf, NaN, NA ... be marked up too?" Like in: # iNA <- as.integer(NA) # !is.na(Inf) & !is.nan(Inf) & is.infinite(Inf) & !is.finite(Inf) # !is.na(-Inf)& !is.nan(-Inf)& is.infinite(-Inf)& !is.finite(-Inf) # is.na(NA) & !is.nan(NA) & !is.infinite(NA) & !is.finite(NA) # is.na(NaN) & is.nan(NaN) & !is.infinite(NaN) & !is.finite(NaN) # is.na(iNA) & !is.nan(iNA) & !is.infinite(iNA) & !is.finite(iNA) What you want to say? -- View this message in context: http://www.nabble.com/highlighting-constants-tp25440669p25440669.html Sent from the R help mailing list archive at Nabble.com.
