Dzvanya munyika yeR yekuongorora data
Nyika yekuongorora nhamba yakakura uye yakaoma, asi mutauro weR wauya kuzorerutsa kuoma uku. Inozivikanwa nesimba rayo uye nyore, R yave imwe yeanonyanya kufarirwa mitauro yekuronga mumunda wekuongorora nhamba. Kosi "Tanga nemutauro weR kuti uongorore data rako" paOpenClassrooms igedhi rekupinda muchiitiko ichi chinonakidza.
Kubva pakutanga, iwe uchaendeswa kuR Studio environment, inofanirwa-ine chigadziro kune chero mushandisi weR. Iwe uchadzidza zvinyorwa zvemutauro, kubva kumhando yezvinhu kusvika kune nzira dzekutumira uye kutumira data. Imwe neimwe module yakagadzirirwa kukupa iwe hunyanzvi hunoshanda, huchikutendera iwe kuti utore, kubvunza uye kuona data rako zviri nyore.
Asi handizvo zvoga. Kupfuura nyore hurongwa, iwe unozotungamirwa kuburikidza neiyo nuances yehuwandu hwekuongorora. Nzira yekududzira sei mhinduro dzako? Iwe unogona sei kuvimbisa kuvimbika kwekuongorora kwako? Iyi mibvunzo, nemimwe mizhinji, ichapindurwa mukosi yese.
Muchidimbu, kana iwe uchitsvaga kugona hunyanzvi hwekuongororwa kwedata, kuita pfungwa dzenhamba dzinoita sedzisingawirirane, kosi iyi ndeyako. Hazvisi zvekungodzidza mutauro mutsva, asi kuzvinyudza iwe munyika umo data rinotaura nekutaura nyaya.
Navigate kusiyana kwezvinhu zveR kuti uwane ongororo yakakwana
Imwe yemabhenefiti makuru emutauro weR iri mukupfuma kwayo maererano nezvinhu. Izvi zvinhu, izvo zvingaita seunyanzvi pakuona kwekutanga, ndizvo chaizvo zvivakwa zvekuvaka zvechero ongororo yenhamba inoitwa neR. Hunyanzvi hwavo saka hwakakosha kune chero anoda data analyst.
Iyo OpenClassrooms kosi inonyudza iwe zvakananga mune ino denga. Iwe unozotanga nekujaira iwe nemhando dzakasiyana dzezvinhu muR, kubva kune akareruka mavheji kusvika kune akaoma dataframes. Mhando yega yega yechinhu ine maitiro ayo uye mashandisiro, uye iwe uchadzidza nzira yekusarudza chinhu chakakodzera kune yega yega mamiriro.
Asi handizvo zvoga. Kukosha kwekusarudzwa kwezvinhu muzvinhu izvi kunosimbiswa zvakare. Kunyangwe iwe uchida kuita sarudzo mune vector, matrix, rondedzero kana dataframe, chaiwo matekiniki anowanikwa kwauri. Iyo kosi inokutungamira iwe kuburikidza neaya matekiniki, ichikubvumidza iwe kutora, kusefa uye kushandura data rako nemazvo.
Pakupedzisira, kugona zvinhu zveR kunopfuura hunyanzvi hwehunyanzvi. Iyi ndiyo kiyi yekusandura data raw kuita muono une musoro.
Kushandura Dhata kuita Zvinyorwa Zvinoonekwa
Ongororo yedata inongodarika kunyengedza nekubvunza nhamba. Chimwe chezvakanyanya kukosha kugona kuona iyi data, kuishandura kuita magirafu uye zviono zvinotaurira nyaya. R, neraibhurari yayo yakakura yemapakeji akatsaurirwa kuona, inokunda munzvimbo ino.
Kosi yeOpenClassrooms inokutora parwendo kuburikidza nezvinogoneka zvekuona zvinopihwa naR. Kubva pamagirafu ekutanga kusvika kune inopindirana yekuona, iwe uchaona maitiro ekuita kuti data rako rive raramo. Iwe unozodzidza kushandisa mapakeji akadai seggplot2, imwe yeanonyanya kufarirwa uye ane simba maturusi ekugadzira machati muR.
Asi kuona hakuregi pakugadzira machati akanaka. Izvo zvakare nezve kududzira izvi zviratidziro, kunzwisisa zvavanoratidza nezve data rako. Iyo kosi inokutungamira iwe kuburikidza neiyi dudziro, ichikubatsira kuona mafambiro, anomalies, uye zvakavanzika maonero mumachati ako.
