... Done group effective
Each item inside the group "effective" is a vector of numbers. I want to convert effective into a data frame or matrix for use with matplot.
However, R sees effective not as a collection of vectors, but as a pairlist. I'm not a Lisp programmer, so don't understand the significance of the list help page's comment about dotted lists.
> class(effective) [1] "pairlist" > attributes(effective) $names [1] "SMD" "PR" "CPR" "AggNonComp" "AggComp"
I can access the elements in effective as list elements, either with effective$SMD or effective[[1]], as in:
> effective[[1]]
[1] 1.000000 1.000000 1.000000 1.000000 1.000000 1.000000 1.000000 1.000000
[9] 1.000000 1.000000 1.000000 1.000000 1.000000 1.000000 1.000000 1.000000
[17] 1.000000 1.000000 1.000000 1.000000 1.000000 1.000000 1.000000 1.000000
[25] 1.000000 1.000000 1.000000 1.000000 1.000000 1.000000 4.761905 4.668534
[33] 4.743833 4.743833 4.694836 4.672897 4.612546 4.612546 4.612546 4.950495
[41] 4.766444 4.761905 4.329004 4.990020 4.930966 4.906771 4.378284 4.686036
[49] 4.935834 4.793864 4.793864 4.541326 4.849661 4.730369 4.960317 4.159734
But I can't force it into a data frame
> as.data.frame(effective)
Error in as.data.frame.default(effective) :
can't coerce pairlist into a data.frame
But I can manually build the dataframe
> data.frame(effective$SMD,effective$PR,effective$CPR,effective$AggNonComp,effective$AggComp)
But that is a bit frustrating for every individual dataset coming in.
Is there a short cut?
