Dear all, Please, I have a doubt regarding symbol plotting with data originating from a table. Please, see below: I have a tab delimited file called table1.txt with 4 columns: ypos animal var1 var2 5 cat gina <= lady gina \u2264 lady 7 dog bill >= tony bill \u2265 tony 9 fish dude <= bro dude \u2264 bro #I then load in the data to R: table1<-read.table("table1.txt", header=TRUE, sep="\t") #if I take a look at the table I realize that \u2264 was replaced by \\u2264 table1 #So, if i try to p...

If i insert \u2264 inside the text, like this lsd_label <- "LSD (P \u2264 0.05) = " the result is "LSD (P = 0.05) = " instead "LSD (P ? 0.05) = " how can i solve this problem? Thanks. -- View this message in context: http://r.789695.n4.nabble.com/less-than-or-equal-to-glyph-tp...

Hello, I am trying to add a less than equal to symbol in a ggplot2 legend text. See sample code below. I have tried using the expression function and \u2264. I also tried adding labels to legend.text under theme. Neither of these 3 options work. Please help, Mahesh ++++++++++++++ Extra.column=ifelse(data[,covariate]>cutpoint,1,0) Grp1 <- "\u2264 1.5" Grp2 <- ">1.5" Extra.column=factor(Extra.column,levels=c(0,...

..."<="(less than or equal to) is replaced by "..." (ellipsis) how can I fix that? postscript("plot1.ps", width = 22, height = 11.5,pointsize=24,paper="special",bg="transparent") plot(NULL,xlim=c(1,10),ylim=c(1,10)) text(5,5,"\u2264") dev.off() I'm using windows vista, my system is in English, R v2.8.1 thanks, Victor

...r2,y=1:11,table1$var1,pos=4) title(x=15,y=5,expression("how to substitute the < = with the " <= "symbol"),font=5) Please, note that the data must come from a table (not manually fed in a text command) I received help yesterday and learned a fix using \u2264, eval, parse, and sprintf? but the symbols generated by this fix are not exported to an .EPS file Kind regards, Victor Faria Seabra, MD

...a call to ggplot() did not display the desired symbol, but an explicitly built legend using the same labels did. Example (I am trying to get the less than or equal to symbol): > .df <- data.frame(afp = c(0,0,1,1), time=c(0,2,0,1), surv=c(1, 0.5, 1, 0.4)) > afpLabels <- c("AFP \u2264 16", "AFP > 16") > afpStrata <- factor(.df$afp, labels=afpLabels) > afpStrata [1] AFP ? 16 AFP ? 16 AFP > 16 AFP > 16 Levels: AFP = 16 AFP > 16 The first level is reported as "AFP = 16". > levels(afpStrata) [1] "AFP ? 16" "AFP > 1...
