• [Andyed] Investigate potential to gather updated stats for metrics tracked in historical research (% usage of bookmarks, % new urls visited, etc.)

Toolset

• R
• GGobi

Code

See the Etherpad Page for the scratchpad

Load Data

places <- read.csv("...places.csv")

Compute age metrics

places$oldest_stamp = as.POSIXct(strptime(as.character(places$visit_date_oldest),format="%m/%d/%y %H:%M"))
places$newest_stamp = as.POSIXct(strptime(as.character(places$visit_date_newest),format="%m/%d/%y %H:%M"))
places$time_delta = difftime(places$newest_stamp,places$oldest_stamp, units="days")

Tags & Bookmark Metrics

places$bookmark_tagged_pct = (places$bookmark_cnt - places$bookmark_nontag_cnt )/ places$bookmark_cnt
places$folder_cnt_crrctd = places$folder_cnt - places$bookmark_cnt
