Good Afternoon,
I am inexperienced in data visualization R. so I wonder if someone can help
me.
I am using the generic database mtcars.
I would like to change the chart plot, instead of appearing the name of the
medicine, I wanted a symbol in the chart drugX arise for example in a yellow
circle, and so for the rest of the drugs.
I am using the following code.
dataset
Age Sex BP Cholesterol Na K Drug
1 23 F HIGH HIGH 0.792535 0.031258 drugY
2 47 M LOW HIGH 0.739309 0.056468 drugC
3 47 M LOW HIGH 0.697269 0.068944 drugC
4 28 F NORMAL HIGH 0.563682 0.072289 drugX
5 61 F LOW HIGH 0.559294 0.030998 drugY
6 22 F NORMAL HIGH 0.676901 0.078647 drugX
7 49 F NORMAL HIGH 0.789637 0.048518 drugY
8 41 M LOW HIGH 0.766635 0.069461 drugC
9 60 M NORMAL HIGH 0.777205 0.051230 drugY
10 43 M LOW NORMAL 0.526102 0.027164 drugY
11 47 F LOW HIGH 0.896056 0.076147 drugC
plot(dataset$Na, dataset$K, main="Na vs K",
xlab="Na", ylab="K", pch=20, col="blue")
text(dataset$Na,dataset$K,dataset$Drug, cex=0.6, pos=4, col="red")
The idea is that instead of writing the name had to be a legend and symbol
was designed in a different color for each drug
Thanks
