Readers,
For data set:
a, 90, 10
b, 60, 40
c, ,
d, , 50
A plot was attempted:
dataset<-as.matrix(read.csv("datafile.csv",header=FALSE))
barplot<-(dataset,horiz=TRUE)
A warning message is returned, about NAs introduced by coercion and an
undesirable graph. The desired output is something similar to:
a ---------*
b ------****
c
d ****
Whereby a legend would be produced to describe '*' and '-'. Any help
please?
