mutate/tibble 中的自定义函数

2024-04-22

我正在关注一个tutorial https://cran.r-project.org/web/packages/broom/vignettes/kmeans.html我正在尝试将这部分应用于我的数据/问题

kclusts <- tibble(k = 1:9) %>%
  mutate(
    kclust = map(k, ~kmeans(points, .x)),
    tidied = map(kclust, tidy),
    glanced = map(kclust, glance),
    augmented = map(kclust, augment, points)
  )

但是我的数据与教程的数据略有不同。我正在尝试应用最后一行augmented = map(kclust, augment, points).

有效的代码（没有最后一行）：

kclust <- results %>%
  as_tibble() %>% 
  select(-id_row) %>% 
  group_by(year_row) %>% 
  nest(.key = "value") %>%
  filter(map_int(value, nrow) > 4) %>% 
  mutate(kmeans = map(value, ~kmeans(.x[[1]], centers = 4, iter.max = 10, nstart = 1)),
         tidied = map(kmeans, tidy),
         glanced = map(kmeans, glance))

代码不起作用（我尝试augment part:

kclust <- results %>%
  as_tibble() %>% 
  select(-id_row) %>% 
  group_by(year_row) %>% 
  nest(.key = "value") %>%
  filter(map_int(value, nrow) > 4) %>% 
  mutate(kmeans = map(value, ~kmeans(.x[[1]], centers = 4, iter.max = 10, nstart = 1)),
         tidied = map(kmeans, tidy),
         glanced = map(kmeans, glance),
         augmented = map(1:nrow(kclust,  function(x) {augment(kclust$kmeans[[x]], kclust$value[[x]])})))

以下内容在 tibble 之外工作，但我无法让它在里面工作；

augment(kclust$kmeans[[1]], kclust$value[[1]])

fun <- function(x) {augment(kclust$kmeans[[x]], kclust$value[[x]])}
ag <- map(1:3, fun)
ag

我的目标是在教程的最后绘制 ggplot 图，其中每年将是一个方面。

p1 <- ggplot(assignments, aes(x1, x2)) +
  geom_point(aes(color = .cluster)) + 
  facet_wrap(~ k)
p1
