dear reserachers,
I am looking for a expression about a special symbol (±) in a Legend and
add on front of "Mean ± SD" the symbol of bracket
sorry if the example is not great
disptest <- matrix(rnorm(10),nrow=10)
disptest.means<- rowMeans(disptest)
plot(1:10,disptest.means)
dispersion(1:10,disptest.means,(disptest.means+disptest
),(disptest.means-disptest ),intervals=FALSE,arrow.cap=0.001,arrow.gap=0)
legend("topleft",
legend=c("Mean","Mean +/- SD"),
pch=c(1,NA),
bty="n",cex=1.3)
thanks for all suggestions
Gianni
