我在窗口初始化方法中创建了一个glContext。
library(tidyverse)
bind_rows(
iris,
iris %>% mutate(Species = "Total")
) %>%
group_by(Species) %>%
summarise(Mean = mean(Sepal.Width),
Median = median(Sepal.Width),
sd = sd(Sepal.Width),
p10 = quantile(Sepal.Width, probs = 0.1))
#> # A tibble: 4 x 5
#> Species Mean Median sd p10
#> <chr> <dbl> <dbl> <dbl> <dbl>
#> 1 setosa 3.43 3.4 0.379 3
#> 2 Total 3.06 3 0.436 2.5
#> 3 versicolor 2.77 2.8 0.314 2.3
#> 4 virginica 2.97 3 0.322 2.59
但是，随后调用glCreateProgram会返回以下内容：
glfwMakeContextCurrent(handle);
GL.createCapabilities();
glfwShowWindow(handle);
在创建着色器程序之前，我从未遇到过此问题。我最近重构了代码，但我将glContext的初始化保持不变。请帮忙！
