Nekuda kwekuvharirwa, vazhinji zvino vanopedza chikamu cheshumba chenguva yavo kumba, uye nguva ino vanogona, uye kunyangwe inofanirwa, kushandiswa zvine mutsindo.
Pakutanga kwekuvharirwa, ndakafunga kupedzisa mamwe mapurojekiti andakatanga mwedzi mishoma yapfuura. Imwe yemapurojekiti aya yaive kosi yevhidhiyo "R Mutauro weVashandisi veExcel". Nekosi iyi, ndaida kudzikisa chipingamupinyi chekupinda muR, uye zvishoma kuzadza kushomeka kuripo kwezvinhu zvekudzidzisa pane iyi nyaya muchiRussia.
Kana zvese zvichishanda nedata mukambani yaunoshandira ichiri kuitwa muExcel, saka ini ndinokurudzira kuti uzive nezvechizvino-zvino, uye panguva imwechete yakasununguka zvachose, data yekuongorora chishandiso.

Nezve iyo kosi
Iyo kosi yakarongeka yakatenderedza zvivakwa tidyverse, uye mapakeji akabatanidzwa mairi: readr, vroom, dplyr, tidyr, ggplot2. Ehe, kune mamwe mapakeji akanaka muR anoita mashandiro akafanana, semuenzaniso data.table, asi mashoko akanyorwa tidyverse intuitive, iri nyore kuverenga kunyangwe kumushandisi asina kudzidziswa, saka ndinofunga zviri nani kutanga kudzidza mutauro weR tidyverse.
Iyo kosi inokutungamira iwe kuburikidza ese ekuongorora data mashandiro, kubva pakurodha kusvika pakuona mhedzisiro yapera.
Sei R uye kwete Python? Nekuti R mutauro unoshanda, zviri nyore kune vashandisi veExcel kuchinjira kwairi, nekuti hapana chikonzero chekunyura mune yechinyakare-inotungamirwa hurongwa.
Parizvino, zvidzidzo zvevhidhiyo gumi nembiri zvakarongwa, kubva pa12 kusvika kumaminitsi makumi maviri imwe neimwe.
Zvidzidzo zvichavhurwa zvishoma nezvishoma. Muvhuro wega wega ndichavhura mukana kune chidzidzo chitsva pawebhusaiti yangu. mune imwe playlist yakasiyana.
Kosi iyi ndeyaani?
Ndinofunga izvi zvakajeka kubva mumusoro, zvisinei, ini ndichazvitsanangura zvakadzama.
Kosi yacho yakanangana neavo vanoshingairira kushandisa Microsoft Excel mubasa ravo uye kuita basa ravo rose nedata ipapo. Kazhinji, kana iwe ukavhura iyo Microsoft Excel application kamwechete pasvondo, saka kosi yacho yakakunakira iwe.
Iwe haufanirwe kuve nehunyanzvi hwekuronga kuti upedze kosi, nekuti ... Kosi yacho yakanangana nevanotanga.
Asi, zvichida, kutanga kubva pachidzidzo 4, pachava nezvinhu zvinonakidza zvevashandisi veR, zvakare, nokuti ... basa guru remapakeji akadai se dplyr ΠΈ tidyr ichakurukurwa zvakadzama.
