Wie man die X-Achsenbeschriftungen um 90 Grad in Levelplot dreht

Question

Ich versuche, eine Korrelationskarte zu visualisieren, und ich denke, dass ich es bis auf das Durcheinander der X-Achsenbeschriftungen zum Laufen gebracht habe. Irgendwelche Vorschläge, wie man sie dreht? Einige der Parameter für viele der Basis-R-Plots scheinen für Levelplots nicht verfügbar zu sein. Es ist möglich, dass ich nicht weiß, wovon ich rede.

Dies ist die Daten, die ich verwendet:

Mein Code:

rgb.palette <- colorRampPalette(c("blue", "yellow"), space = "rgb") 
levelplot(cor2, aspect="iso", main="Correlation Matrix", xlab="", xaxt='n', ylab="", col.regions=rgb.palette(120), cuts=100, at=seq(0,1,0.01)) #, names.arg=paste(cor2[,1]),las=3 

#this is what I tried, and it didn't work. I couldn't get names(cor2) to work, but I guess that this is a separate question. 
labs<- (cor2[,0]) 
text(cex=1, x=x-0.25, y=-1.5, labs, xpd=TRUE, srt=90) 

##want something like this, but can't find an analogous way to remove axisnames and add text 
#x <- barplot(table(mtcars$cyl),axisnames=FALSE)#,xaxt="n" 
#labs <- paste(names(table(mtcars$cyl)), "cylinders") 
#text(cex=1, x=x-0.25, y=-1.5, labs, xpd=TRUE, srt=90) 

Answer 1

Was die Drehung der x-Achse Etiketten gehen, haben Sie scales Parameter verwenden (siehe ?xyplot für weitere Informationen über lattice Parameter). Sie möchten nur die x Komponente ändern: scales=list(x=list(rot=90)). Im Kontext:

levelplot(cor2, 
      aspect="iso", scales=list(x=list(rot=90)), 
      main="Correlation Matrix", col.regions=rgb.palette(120), 
      cuts=100, at=seq(0,1,0.01))
