Dear useRs,
I have defined two matrices "prop" and "ELE" in the following manner
> dput(prop)
structure(c(122.466666666667, 87.1500875, 94.3647755102041, 84.8471625,
95.2767755102041, 84.15558125, 121.846666666667, 90.75970625, 98.2028979591837,
87.1500875, 88.2953043478261, 72.81219375, 88.234, 85.73326875,
82.4549743589744, 82.6041125, 96.1123888888889, 62.77575625, 86.9222790697674,
64.74370625, 57.2601860465116, 58.98126875, 91.7883555555556, 84.8471625,
92.170347826087, 84.15558125, 91.398085106383, 91.79875, 108.423025641026,
72.81219375), .Dim = c(2L, 15L), .Dimnames = list(c("ori", "sat"), c("Ba",
"Gd", "Ko", "Mu", "Mz", "Bg", "Do", "Gk", "Ka", "Mn", "Na", "Rw", "Rb", "Kh",
"Sk")))
> dput(ELE)
c(995.4, 813.5, 614, 2291, 702, 1038, 2571, 461, 700, 171, 2500, 1615, 587,
1209, 1981)
Then I gave the following commands to make a plot
colours <- c("black", "grey")
barplot(prop,ylab = "Numbers", cex.lab = 1.5, cex.main = 1.4, beside=TRUE,
col=colours,ylim=c(0,250))
axis(side=3,xlim=c(0,45), at=c(6,12,18,24,30,36,42),
labels=c("Gd","Mu","Bg","Gk","Mn","Rw","Kh"))
axis(side=3,xlim=c(0,45), at=c(6,12,18,24,30,36,42),
labels=c("Gd","Mu","Bg","Gk","Mn","Rw","Kh"))
par(new=TRUE)
barplot(ELE, pch=15, xlab="", ylab="",
axes=FALSE, type="b", col="red",yaxt = "n",ylim = rev(c(0,4500)))
mtext("Cell Density",side=4,col="red",line=1)
axis(4, ylim=c(0,7000), col="red",col.axis="red",las=1,cex.lab=0.5,cex.axis=0.7)
The problem is that the second Y-axis is somewhat located outside the plot and
not visible. I kindly, require your help on it.
Thanks in advance,
Eliza
