Hauv cov ntawv tshaj tawm no peb yuav tshuaj xyuas qee qhov haujlwm uas coj peb mus rau kev tshuaj xyuas thawj rooj plaub

  1. Kauj Ruam 1 – Thawj txoj kev mus rau cov ntaub ntawv .
  2. Kauj Ruam 2 - Kev txheeb xyuas qhov sib txawv categorical.
  3. Kauj Ruam 3 - Txheeb xyuas cov lej sib txawv.
  4. Kauj Ruam 4 - Txheeb xyuas cov lej thiab categorical tib lub sijhawm.

Cov lus nug tseem yog, R siv li cas hauv cov ntaub ntawv txheeb xyuas?

R yog lus siv rau statistical xam, cov ntaub ntawv tsom xam thiab graphical sawv cev ntawm cov ntaub ntawv . Tsim nyob rau xyoo 1990 los ntawm Ross Ihaka thiab Robert Gentleman, R tau tsim los ua ib qho kev txheeb cais platform rau cov ntaub ntawv ntxuav, tsom xam , thiab sawv cev. Qhov no qhia tau hais tias nrov npaum li cas R programming yog nyob rau hauv cov ntaub ntawv science.

Koj yuav tshuaj xyuas cov ntaub ntawv li cas? Txhawm rau txhim kho koj cov kev txawj tsom xam cov ntaub ntawv thiab ua kom yooj yim rau koj cov kev txiav txim siab, ua cov tsib kauj ruam hauv koj cov txheej txheem txheeb xyuas cov ntaub ntawv:

  1. Kauj Ruam 1: Qhia koj cov lus nug.
  2. Kauj ruam 2: Teem kom meej qhov ntsuas qhov tseem ceeb.
  3. Kauj ruam 3: Sau cov ntaub ntawv.
  4. Kauj Ruam 4: Tshawb xyuas cov ntaub ntawv.
  5. Kauj Ruam 5: Txhais cov txiaj ntsig.

Qhov thib ob, Kuv yuav txheeb xyuas cov ntaub ntawv hauv Excel li cas siv R?

Cov lus qhia rau kev txheeb xyuas cov ntaub ntawv Excel hauv R

  1. Txhawm rau import cov ntaub ntawv Excel rau hauv R, siv lub pob readxl.
  2. Txhawm rau xa cov ntaub ntawv Excel los ntawm R, siv lub pob openxlsx.
  3. Yuav ua li cas tshem tawm cov cim xws li "$" thiab "%" los ntawm cov txiaj thiab feem pua txhua kab hauv Excel, thiab hloov lawv mus rau cov lej sib txawv tsim nyog rau kev txheeb xyuas hauv R.

Kuv yuav tsum kawm R lossis Python?

Nyob rau hauv ib tug nutshell, nws hais tias, Python yog zoo dua rau cov ntaub ntawv manipulation thiab rov ua hauj lwm, thaum R yog qhov zoo rau ad hoc tsom xam thiab tshawb nrhiav cov ntaub ntawv. R muaj qhov siab kev kawm nkhaus, thiab cov neeg tsis muaj kev paub txog kev ua haujlwm yuav pom nws yooj yim. Python feem ntau suav hais tias yooj yim rau khaws.
