I'm trying to create a histogram from the following code, but my data keeps
adding the Num vector and plotting that. My data in the CSV file is just
one vector. Does anyone know why?
Thanks
Conrad
SPXdf = data.frame(read.csv(file = "SPX.csv", header = TRUE, sep = ",", dec
= ".", fill = TRUE))
Max = max(SPXdf[,2])
Min = min(SPXdf[,2])
Count = length(SPXdf[,2])
sig = sd(SPXdf[,2])
BinSize = (3.5*sig)/(Count^(1/3))
BinNum = (Max - Min)/(BinSize)
Bins = seq(Min,Max,by = BinSize)
Count2 = length(Bins)
Num = mat.or.vec(1,Count2)
for (i in 1:Count){
for (j in 1:Count2){
if ((SPXdf[i,2] < Bins[j]))
{Num[j] = Num[j] + 1}
}
}
barplot(Num,Bins, xlab = "SPXdf", ylab = "Frequency")
