Hi Ujjwal,
Given that you have asked about a barplot and included standard errors, you
probably want something like the following:
uk.df<-read.table(text=
"habitat,proportion_use,proportion_use_SE,selectivity_index,selectivity_index_SE
grassland,0.56,0.22,0.72,0.29
sal_forest,0.11,0.04,-0.43,0.13
bamboo-mix,0.22,0.07,0.05,0.02
miscellaneous,0.11,0.03,-0.59,0.18",sep=",",header=TRUE)
library(plotrix)
barpos<-barp(uk.df[c("proportion_use","selectivity_index")],
names.arg=c("proportion_use","selectivity_index"),
main="Habitat Use Plot",ylab="Proportion of use",
col=2:5,ylim=c(-1,1.1))
dispersion(barpos$x,barpos$y,
ulim=as.matrix(uk.df[c("proportion_use_SE","selectivity_index_SE")]))
legend(0.7,-0.3,uk.df$habitat,fill=2:4)
You will almost certainly be told that you shouldn't do this, so maybe you
should consider:
matplot(matrix(c(0.9,1.1,1.9,2.1,2.9,3.1,3.9,4.1),nrow=4,byrow=TRUE),
uk.df[c("proportion_use","selectivity_index")],
ylab="Proportion and selectivity of use",
ylim=c(-1,1.1),pch=18:19,col=2:3,xaxt="n",xlab="Habitat",
main="Habitat Use Plot")
axis(1,at=1:4,labels=uk.df$habitat)
dispersion(matrix(c(0.9,1.1,1.9,2.1,2.9,3.1,3.9,4.1),nrow=4,byrow=TRUE),
as.matrix(uk.df[c("proportion_use","selectivity_index")]),
ulim=as.matrix(uk.df[c("proportion_use_SE","selectivity_index_SE")]))
legend(2.5,1,c("Proportion of use","Selectivity of use"),
pch=18:19,col=2:3)
