Dear R- Experts, Seek your help. I want to creata data as follows. Ref_array with 4 columns. 1st column should store data of precision: 8.4 (i.e. 8 digits before decimal point and 4 digits after decimal points) 2nd column: should store data of type date "yyyy-mm-dd hh:mm:ss" 3rd column: only integer value. No decimal points 4th column: percentage values
In R, an array is all one data type, so you can't do that. However, you can have a dataframe that comes close: but there is no special type for 8.4 or percentage values, you'd need to use floating point (or fancy handling of integers) for those. Duncan Murdoch
