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)
