I am trying to dp a 3d plot.
  I tried persp but my data is not a matrix.
  the 3dplot function returns this error, (list) object cannot be coerced to 'double'
  heres my code,
  td<-read.csv("td.csv", header=TRUE)
price<-read.csv("price.csv", header=TRUE)
contractdate<-read.csv("contractdate.csv", header=TRUE)
library(rgl)
plot3d(td,contractdate,price)
   
  the 3 csv data files have the following format,
  1
  2
  3
  4
  5
  6
  ...
  60,000
   
  basically I have 3 columns, x y and z that have 60000 rows (data points) I want to plot.
