I want to open a csv that has 5 columns, three of them have values with three decimals and when I try to open it with "read.csv", one of them opens it with a decimal, another with none and the other with the three, like this:
             V1      V2      V3  V4  V5
1      377946.8 4109939 687.679 -89  15
2      377946.8 4109939 687.678 -89  23
3      377946.8 4109939 687.676 -89 123
4      377946.8 4109939 687.697 -89  84
5      377946.8 4109939 687.687 -89  30
6      377946.8 4109939 687.661 -89  46
can someone tell me what is the problem and the solution?
