I'm sure this has been asked before. If you can find a good link I'll happily delete the question but I'm not having any luck with Google. I have a CSV file named "myData.csv", i can read the data in that file from R 

myData <- read.csv (fil.choose(), header=T)

But how can i draw any 3 D plot from the data that i have already read using R i don't want to rewrite the data again in R, i just need to manipulate myData

myData.csv

x    y    value
0    0    4.35
0    1    4.23
0    2    4.24
1    0    4.34
1    1    4.23
1    2    4.22
2    0    4.34
2    1    4.22
2    2    4.22

    Please clarify `i just need to manipulate myData`... – zx8754 Apr 30 '15 at 16:16
  • @zx8754 i meant since i read the data from myData.csv i want to plot a 3 D histogram using the table above – Geek Apr 30 '15 at 16:19
  • Do you want to make some random 3D plot, using `myData`? – zx8754 Apr 30 '15 at 16:20
  • @zx8754 I am a beginner, it's my first time using R I want to plot at first any random graph just to make sure that it works . But then the plot that i will need is a 3 D histogram Hence, i'd be more than happy if you can help me with that – Geek Apr 30 '15 at 16:23

  • @BurakArslan It's not the same issue i think, because i want to use a ready data in a csv file not writing data at real time it is quite different isnt it ? – Geek Apr 30 '15 at 16:37
  • Knowing you got the data from csv doesn't change the answer. However, a surface plot (from your title) is not the same as a histogram plot (from your comment). The relevant dupe for the former is probably: http://stackoverflow.com/questions/23295737/3d-surface-plot-in-r – Frank May 01 '15 at 17:02
