basic dataframe question
....frame(cbind(Cu = CuZn$Cu, CuCen = CuZn$CuCen, StartCu, EndCu)) class(CuZn$CuCen) #returns "logical" class(CuIEP$CuCen) #returns "numeric" CuIEP2 = data.frame(cbind(Cu = CuZn$Cu, CuCen = as.logical(CuZn$CuCen), StartCu, EndCu)) class(CuIEP2$CuCen) #returns "numeric" CuIEP3 = data.frame(cbind(Cu = CuZn$Cu, CuCen = I(CuZn$CuCen), StartCu, EndCu)) class(CuIEP3$CuCen) #returns "numeric" I think that I might be missing something fairly fundamental about data coercion in R. ... would love to figure this out. Any assistance would be appreciated. Thanks much,...
