[R] Change the position of label when using R package eulerr

[Aimin Yan]

Thank you,

I figure out a way like this:

fit1 <- euler(c("ciLAD" = 785, "LAD" = 565, "nonXL_MEF" = 167,
                    "ciLAD&LAD" = 3, "ciLAD&nonXL_MEF" = 101,
"LAD&nonXL_MEF" = 541,
                    "ciLAD&LAD&nonXL_MEF" = 2),shape = "ellipse")

plot(fit1,quantities = TRUE,fill = rainbow(7),lty = 1:2,labels = list(font
= 1),alpha=0.7)

grid.ls()
t <- grid.get("quantities.grob")
names(t)

# Change these value will change the location of label.

grid.edit("quantities.grob",x=unit.c(unit(-14.9884684724791, "native"),
                                         unit(-14.883684319653, "native"),
                                         unit(13.9805892820006, "native"),
                                         unit(-12.8808987356981, "native"),
                                         unit(-11.488226371243, "native"),
                                         unit(-9.51474016085318, "native"),
                                         unit(-1.00436055190216, "native")))

grid.edit("quantities.grob",y=unit.c(unit(-8.07672595120493, "native"),
                                         unit(4.78718651828883, "native"),
                                         unit(0.25941593099694, "native"),
                                         unit(-4.32200781461293, "native"),
                                         unit(25.7349463488991, "native"),
                                         unit(-22.7610031110325, "native"),
                                         unit(14.5001560838519, "native")))

However, here I just want to change the x and y  value of 4th label, does
anyone know how to set it?
