R Markdown

This is an R Markdown document. Markdown is a simple formatting syntax for authoring HTML, PDF, and MS Word documents. For more details on using R Markdown see http://rmarkdown.rstudio.com.

When you click the Knit button a document will be generated that includes both content as well as the output of any embedded R code chunks within the document. You can embed an R code chunk like this:

# for, if를 활용하는 경우 dataframe을 통해서만 가능. tibble x
# ncol : column(열의 개수, 즉 변수의 개수를 세는 함수. dataframe만 취급)
# cbind : 열 결합(변수 간 결합)
# nrow :  dataframe의 행의 수를 출력하는 함수(n수)
# rbind : 행 결합
# merge : 동일 key값 기준 결합
data1<-data.frame(tibbledata)
dataname_num<-NULL
for(x in 1:ncol)
  ){ if(is.numeric(noname_data[, x])) no_num <- cbind(no_num, noname_data[, x])}
  
summary(cars)

Including Plots

You can also embed plots, for example:

Note that the echo = FALSE parameter was added to the code chunk to prevent printing of the R code that generated the plot.
