globaltrends 0.1.0

• Removed globaltrends from CRAN

Change in downloading approach

• Run downloads from Google Trends through the official Google Trends API
  • Access available from Google: https://support.google.com/trends/contact/trends_api
  • Downloads are made with the Google API Python Client
  • globaltrendsuses reticulate to run the respective Python script
• Users can choose to download through the official API or the gtrendsrpackage
  • If users call initialized_python(), the downloads will be made through the official Google Trends API
  • If users run downloads without calling initialized_python(), the downloads will be made through the gtrendsrpackage
• Control the waiting time between queries through the environmental variable gt.env$query_wait (default value = 0.1s)

Package simplifications

• Remove time-series adjustments from compute_score for package simplification
• Remove get_abnorm_hist function for package simplification
• Remove plotting functions and export classes for package simplification
• Accelerate compute_score
• Accelerate handling of synonyms in separate function aggregate_synonyms

Technical issues and bug fixes

• Increase dependencies to dplyr 1.1.1 and replace the multiple argument by relationship
• Fixed issues in sample data

globaltrends 0.0.14 (2023-03-06)

• Remove dependency on glue package, calls of glue::glue are replaced with paste and paste0
• Remove dependency on ineq package, calls of ineq::ineq are replaced with internal functions
• Use functions from DBI 1.1.0: dbCreateTable and dbAppendTable
• Remove the function plot_map from the package:
  • The function proofed too inflexible, only world map was included
  • We point users to the functions from the packages maps and ggmap
  • Remove dependency on the maps package
• Remove reference to non-existent table data_global in function remove_data

globaltrends 0.0.13 (2023-02-23)

• Set minimum dependency of stats and utils to version 3.5.0 in line with minimum R dependency
• Store globaltrends logo in the vignettes folder
• Add explanation of Google's data preparation methodology to vignette
• Change wait intervals for status responses != 200 and add message about automatic retry of download
  • Status == 500: wait 1 second
  • All other responses: wait 60 seconds
• Add function vacuum_data to free unused memory after remove_data
• Remove all usage of .data to comply with tidyselect 1.2.0, this applies to calls of:
  • dplyr::rename
  • dplyr::select
  • purrr::map
  • purrr::walk
  • tidyr::nest
  • tidyr::pivot_longer
  • tidyr::pivot_wider
  • tidyr::unnest
• As a consequence of the changes in tidyselect 1.2.0, several objects are defined as global variables (see globals.r for details)
• Replace size with linewidth to comply with ggplot2 3.4.0
• Add the argument multiple = "all" and multiple = "error" to comply with dplyr 1.1.0
• Facilitate handling of location = "NA - Namibia", the function add_locations does automatically drop the location
• Remove dependency on WDI package, references to WDI::WDI_data are replaced by data objects countries and countries_wdi

globaltrends 0.0.12 (2022-06-23)

• Stop direct exports from functions to .GlobalEnv
• Exports of objects (e.g., SQL connections, keyword tables) are redirected to package environment gt.env
• Add handle for Namibia ISO code

globaltrends 0.0.11

• Add function plot_map()
• Add automatic stringr::str_squish for keywords and synonyms
• Add documentation on usage of search topics

globaltrends 0.0.10

• Change indication and handling of synonyms (synonyms are now ignored in export_score and export_voi)

globaltrends 0.0.9

• Fasten computation of search scores for data with synonyms
• Fix bugs for control keywords that have a mean of 0 for their search volume time series

globaltrends 0.0.8

• Adapt export_xxx for vector and list inputs
• Optimize RAM usage of export_xxx
• Check whether "db/globaltrends_db.sqlite" file exists in working directory
• Inclusion of "workaround" plot functions that set class xxx automatically:
  • plot_xxx_box
  • plot_xxx_bar
  • plot_xxx_ts

globaltrends 0.0.7

• Change waiting times for errors
  • Status Code != 200/Limit exceeded -> 60 seconds wait
  • Status Code == 500 -> 1 second wait

globaltrends 0.0.6

• To distinguish them from the actual database tables, names of the example data object were adapted. Documentation is still available for the respective database table.
  • batch_keywords -> example_keywords
  • batch_time -> example_time
  • data_control -> example_control
  • data_doi -> example_doi
  • data_object -> example_object
  • data_score -> example_score
• Waiting period between downloads reduced from 20-30 seconds to 5-10 seconds

globaltrends 0.0.5

• Added classes for output from export_xxx
  • export_score -> class("exp_score")
  • export_voi -> class("exp_voi")
  • export_doi -> class("exp_doi")
• export_xxx + get_abnorm_hist supersedes export_xxx_change
  • method for export_score -> class("exp_score")

  • method for export_doi -> class("exp_doi")
  • method for export_doi -> get_abnorm_hist -> class("abnorm_doi")
• plot_box supersedes plot_voi_box and plot_doi_box
  • method for export_score -> class("exp_score")
  • method for export_score -> get_abnorm_hist -> class("abnorm_score")
  • method for export_voi -> class("exp_voi")
  • method for export_voi -> get_abnorm_hist -> class("abnorm_voi")
