I te nuinga o nga wa, i te wa e mahi ana koe me te whakautu mai i te API, me etahi atu raraunga he hanganga rakau uaua, kei te anga koe ki nga whakatakotoranga JSON me XML.
He maha nga painga o enei whakatakotoranga: he pai te penapena raraunga ka taea e koe te karo i nga korero taapiri kore.
Ko te kino o enei whakatakotoranga ko te uaua o a raatau tukatuka me te tātari. Kaore e taea te whakamahi i nga raraunga kore hanga ki nga tatauranga, kaore e taea te hanga tirohanga ki runga.
Ko tenei tuhinga he haere tonu o te whakaputanga . Ka awhina i a koe ki te kawe mai i nga hanganga raraunga kore hanga ki roto i te ahua mohio me te pai mo te tātari i te puka ripanga ma te whakamahi i te kete tidyr, kei roto i te matua o te whare pukapuka tidyverse, me te whanau o nga mahi unnest_*().
Tuhinga
Mena kei te pirangi koe ki te tātari raraunga, ka aro pea koe ki taku и hongere. Ko te nuinga o nga korero e whakatapua ana ki te reo R.
Whakataki
Tapawhā (te tuhipoka a te kaiwhakamaori, kaore au i kite i nga whiringa whakamaori tika mo tenei kupu, no reira ka waiho noa.) Ko te tukanga ki te kawe mai i nga raraunga kaore i hangai me nga huinga kohanga ki roto i te ripanga ahu-rua kei roto i nga rarangi me nga pou e mohio ana. IN tidyr He maha nga mahi hei awhina i a koe ki te whakawhanui i nga rarangi rarangi kohanga me te whakaiti i nga raraunga ki te ahua tapawhā, te ahua ripanga:
unnest_longer()ka mau ia huānga o te rārangi tīwae ka hanga he haupae hōu.unnest_wider()ka tango ia huānga o te rārangi tīwae me te hanga tīwae hōu.unnest_auto()ka whakatau aunoa ko tehea mahi e pai ana ki te whakamahi
unnest_longer()raneiunnest_wider().hoist()rite kiunnest_wider()engari ka kowhiri i nga waahanga kua tohua ka taea e koe te mahi me etahi taumata o te kohanga.
Ko te nuinga o nga raruraru e pa ana ki te kawe mai i nga raraunga kaore i hangaia me te maha o nga taumata o te kohanga ki roto i te ripanga-rua ka taea te whakatau ma te whakakotahi i nga mahi kua whakarārangihia me te dplyr.
Hei whakaatu i enei tikanga, ka whakamahia e matou te kete repurrrsive, e whakarato ana i nga rarangi matatini maha, taumata-maha i ahu mai i te API tukutuku.
library(tidyr)

library(repurrrsive)Kaiwhakamahi GitHub
Kia timata ma gh_kaiwhakamahi, he rarangi kei roto nga korero mo nga kaiwhakamahi GitHub e ono. Tuatahi ka huri tatou i te rarangi gh_kaiwhakamahi в tipa tāpare:
users <- tibble( user = gh_users ) Ko te ahua he iti nei te whakaaro: he aha te whakatakoto rarangi gh_kaiwhakamahi, ki te hanganga raraunga uaua ake? Engari he painga nui te anga raraunga: he whakakotahi i nga vectors maha kia whai waahi nga mea katoa ki te mea kotahi.
Ia huānga ahanoa users he rarangi ingoa e tohu ana ia huānga ki tetahi pou.

Whakaritenga rarangi gh_repos ka timata ano tatou ma te huri ki tibble:

Ko ia putunga he tirohanga motuhake, no reira i runga i te ariā o te raraunga tau (tata ki te raraunga pai) me noho hei rarangi hou, na reira ka whakamahia e matou unnest_longer() a kaore unnest_wider():
repos <- repos %>% unnest_longer(repo)
