RMarkDown Common PDF Export Error

Error ตอน Export PDF

Problem: No LaTeX installation detected ตอน Knit to PDF

No LaTeX installation detected (LaTeX is required to create PDF output). You should install a LaTeX distribution for your platform: https://www.latex-project.org/get/

  If you are not sure, you may install TinyTeX in R: tinytex::install_tinytex()

  Otherwise consider MiKTeX on Windows - http://miktex.org

  MacTeX on macOS - https://tug.org/mactex/
  (NOTE: Download with Safari rather than Chrome strongly recommended)

Solution:

• ลองตามที่มันแนะนำ tinytex::install_tinytex()
• อ๋อ เหมือน RMarkDown มีปัญหา กับภาษาไทยนะ

Backtrace:

Solution:

• ตอน Step Install Require Package ให้เติม repos = "http://cran.us.r-project.org" แต่ถ้า package อยู่ที่อื่นต้องแก้ URL นะ

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = FALSE)

install.packages("nycflights23",repos = "http://cran.us.r-project.org")
install.packages("dplyr",repos = "http://cran.us.r-project.org")
install.packages("ggplot2",repos = "http://cran.us.r-project.org")
install.packages("tidyr",repos = "http://cran.us.r-project.org") 
library(nycflights23)
library(dplyr)
library(ggplot2)
library(tidyr)
```
