Corrplot in R not working
I am trying to work out the correlation between these three labels using corrplot:
train.Item_ID train.Price train.Number_Of_Sales
30495 165.123 1
30375 68.666 5
30011 253.314 2
30864 223.122 1
30780 28.75 1
But somehow its not showing cross correlation between different labels.
corrplot(cor(newtrain),method = "number")
Basically it just shows 1,1,1 but no cross correlation and then size comes so smaller. Please suggest.
Solution
It seems that you have a mess in your data. I got your data and it all works perfect:
library(corrplot)
d <- "train.Item_ID train.Price train.Number_Of_Sales
1 30495 165.123 1
2 30375 68.666 5
3 30011 253.314 2
4 30864 223.122 1
5 30780 28.75 1"
d <- read.table(text = d, header = T)
corrplot(cor(d), method = "number")
