R help - Dec 2007 - 3d plotting

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.

I hope that you actually haven't got any comma to separate the
thousands... it separates fields in a csv files (as the "Comma
Separated Values" name may suggest). If so, get rid of the commas.

You have to coerce the 1-column dataframes created by read.csv to
numeric vectors or to a 60000x3 dataframe.
solution 1:

myData <- cbind(td,contractdate,price)
> library(rgl)
plot3d(mydata)

solution 2:

td <- as.numeric(td)
...
price <- as.numeric(price)
plot3d(td,contractdate,price)
