2. useR! 2015 Dr. Jennifer (Jenny) Bryan Dept. of Statistics &

   Michael Smith Laboratories, UBC jenny@stat.ubc.ca @JennyBryan http://stat545-ubc.github.io @STAT545 http://www.stat.ubc.ca/~jenny/ @jennybc googlesheets
   Google Spreadsheets R API

3. + googlesheets = R wrapper around the Sheets & Drive

   APIs +
4. None

5. Why would a UseR use a Google Sheet? collaboration -

   link, don’t attach! built-in functions to import web data - importxml(), importhtml(), importfeed() magic templates - TAGS, Amazon Price Tracker web services - ifttt.com

6. Why important to have an R interface to Google Sheets?

   Just. Because. Lightweight data store for Shiny

7. The participant who loses the most weight (as measured by

   the final weight as a percentage of his starting weight) shall be declared the winner. Jim Craig

8. Craig won :(

9. “Examples of permitted services include, but are not limited to,

   cooking, gardening, handiwork, caddying, office work, serving food and drinks or running errands.”

10. ~1800 consecutive days of weight data

11. iOS Android enter data from a phone enter data w/o

    WiFi

12. library(googlesheets) ... jc_ss <- gs_title("jim-craig-weight-loss") jc_dat <- gs_read(jc_ss) jc_dat <-

    jc_dat %>% mutate(date = as.Date(date, format = "%m/%d/%Y")) %>% gather("who", "weight", Jim, Craig) p <- ggplot(jc_dat, aes(x = date, y = weight, color = who)) + geom_point(alpha = 0.35) + geom_smooth(se = FALSE, lwd = 2) + scale_y_continuous(labels = lbs_formatter) print(direct.label(p))
13. None

14. I wanted live stats!

15. vn_ss <- gs_title("2015-05-23_seaRM-at-vanNH") #> Sheet successfully identifed: "2015-05-23_seaRM-at-vanNH" game_play <-

    gs_read(vn_ss, ws = 10, range = cell_limits(c(2, NA), c(1, 2))) #> Accessing worksheet titled "10" head(game_play) #> Source: local data frame [6 x 2] #> #> Offense Defense #> 1 NA 42P #> 2 21pu NA #> 3 NA 29pu #> 4 NA 31 #> 5 NA 29 #> 6 NA 31

16. point_info <- vn_ss %>% gs_read_cellfeed(ws = 10, range = "D1:D4")

    %>% gs_simplify_cellfeed(col_names = FALSE) #> Accessing worksheet titled "10" point_info #> D1 D2 D3 D4 #> "Seattle Rainmakers" "1" "3:12:00" "1:49:00"

17. install.packages(“googlesheets”)   library(devtools)   install_github(“jennybc/googlesheets”) not there yet but it’s

    in process

18. gs_*

22. gs_gap()   gs_gap_key()   gs_gap_url() Gapminder Sheet available for examples,

    testing, practice

23. ss  <-­‐  gs_gap()   ss  <-­‐  gs_gap_key()  %>%  gs_key()  

    ss  <-­‐  gs_gap_url()  %>%  gs_url()   ss  <-­‐  gs_gap()   ss  <-­‐  gs_key(gs_gap_key())   ss  <-­‐  gs_url(gs_gap_url())

24. gs_upload() .xls .xlsx .xlt .xltx .xltm .xlsm .csv .tsv .txt

    .tab .ods

25. gs_download() .csv .pdf .xlsx

26. gs_new()           gs_copy()   gs_upload()

27. gs_delete()   gs_grepdel()   gs_vecdel()

28. gs_ws_*

29. gs_ws_ls()   gs_ws_new()   gs_ws_rename()   gs_ws_delete()

30. gs_read()

31. gs_read(...,  ws  =  3,  ...)   gs_read(...,  ws  =  “Europe”,

     ...)   gs_read(...,  range  =  "D12:F15")   gs_read(...,  range  =  "R1C12:R6C15")   gs_read(...,  range  =  cell_limits(c(1,  6),  c(1,  15)))   gs_read(...,  range  =  cell_limits(c(3,  NA),  c(NA,  10)))   gs_read(...,  range  =  cell_rows(1:100))   gs_read(...,  range  =  cell_cols(3:8))   gs_read(...,  range  =  cell_cols("B:MZ"))   gs_read(...,  range  =  anchored("B4",  dim  =  c(2,  10)))

32. gs_new()   gs_ws_new()   gs_edit_cells()   gs_add_row()

33. gs_auth()   gs_user()

34. Technical bits of interest flexible auth flow: - interactive -

    unattended “batch” use - Shiny use we are actually testing - against the Sheets and Drive APIs - including operations that require authentication - on Travis-CI
