I would like to read it (the data) iinto a different application (not 'R'). Within 'R' I can
mlist[[1]] > mlist[1] [[1]] [[1]]$Sku [1] "0" [[1]]$Shape [1] 250.0586 [[1]]$Scale [1] 91.9914 [[1]]$DayOfYear [1] 250 OR mlist[[2]] > mlist[[2]] $Sku [1] "100008" $Shape [1] 178.9637 $Scale [1] 58.76785 $DayOfYear [1] 82 89 93 108 123 123 125 185 186 260 261 266 266 270 270 270 270 273 276 276 276 277 277 277 277 278 278 279 341 357 > I essentially want to mimic this structure with the write.table but that is not what I am seeing. If I take the variable length list off then I get what appears to be a autogenerated list of headers for every row in the file. It is like the fact that this is a list of lists is forgotten. For each line of the file being something like (for the first two list elements above) 0,250.0586,91.9914,250 100008,178.9637,58.767,85,82 ,89 ,93,108,123,123,125,185,186,260,261,266,266,270,270,270,270,273,276,276,276,277,277,277,277,278,278,279,341,357 Where 100008 is the part number (Sku), 178.9637 is the Shape, 58.767 is the Scale, and the remaining is the day of year list (variable length). There would be one of these rows for every part number. If I use dput I get more than I want and it doesn't mean anything to the external application that I am exporting the data to. Similarily 'dump' gives me a bunch of 'R' specific information about the data structure that an external application will not necessarily know what to do with. I just want a simple one row output as able. If I just write.table(mlist,.....) then I get the aforementioned warning about different lengths. If I iterate though the list: for(i in 1:length(mlist)) { write.table(mlist[[i]].....) } Then I get a "50 or more warnings" error. 50: In write.table(mlist[[i]], "SkuSalesInfo.dat", row.names = FALSE, ... : appending column names to file The file that is generated is HUGE (> 250Mb). It seems to be duplicating the row the by the number of elements in the variable list. So instead of one row I get: "Sku","Shape","Scale","DayOfYear" "100008",178.963659119674,58.7678453522722,82 "100008",178.963659119674,58.7678453522722,89 "100008",178.963659119674,58.7678453522722,93 "100008",178.963659119674,58.7678453522722,108 "100008",178.963659119674,58.7678453522722,123 "100008",178.963659119674,58.7678453522722,123 "100008",178.963659119674,58.7678453522722,125 "100008",178.963659119674,58.7678453522722,185 "100008",178.963659119674,58.7678453522722,186 "100008",178.963659119674,58.7678453522722,260 "100008",178.963659119674,58.7678453522722,261 "100008",178.963659119674,58.7678453522722,266 "100008",178.963659119674,58.7678453522722,266 "100008",178.963659119674,58.7678453522722,270 "100008",178.963659119674,58.7678453522722,270 "100008",178.963659119674,58.7678453522722,270 "100008",178.963659119674,58.7678453522722,270 "100008",178.963659119674,58.7678453522722,273 "100008",178.963659119674,58.7678453522722,276 "100008",178.963659119674,58.7678453522722,276 "100008",178.963659119674,58.7678453522722,276 "100008",178.963659119674,58.7678453522722,277 "100008",178.963659119674,58.7678453522722,277 "100008",178.963659119674,58.7678453522722,277 "100008",178.963659119674,58.7678453522722,277 "100008",178.963659119674,58.7678453522722,278 "100008",178.963659119674,58.7678453522722,278 "100008",178.963659119674,58.7678453522722,279 "100008",178.963659119674,58.7678453522722,341 "100008",178.963659119674,58.7678453522722,357 The header seems to be duplicated for each element also.
