TestData <- data.frame("Group" = sample(paste0("Group", 1:3), n, replace = TRUE),
                       "Data1" = sample(1:10, n, replace = TRUE),
                       "Data2" = sample(LETTERS[1:24], n, replace = TRUE))

###ggplot2:colorに適応
```{r}
renderPlot({
  ggplot(TestData,
         aes(x = Data1, y = Data2, col = Group)) +
    geom_point(size = 10) +
    theme_bw() +
    scale_color_manual(values = eval(parse(text = paste0("jgcricol()", "$",
                                                         input$Colpal)))) +
    labs(title = paste0("パレット名：", input$Colpal)) +
    theme_bw(base_family = "Yu Gothic")
})
```

###ggplot2:fillに適応
```{r}
renderPlot({
  ggplot(TestData,
         aes(x = Data2, fill = Group)) +
    geom_bar(stat = "count") + theme_bw() +
    scale_fill_manual(values = eval(parse(text = paste0("jgcricol()", "$",
                                                         input$Colpal)))) +
    labs(title = paste0("パレット名：", input$Colpal)) +
    theme_bw(base_family = "Yu Gothic")
})
