recreate()闪黑屏

如果您在使用recreate()函数时遇到了闪黑屏的问题，可能是因为您的应用程序重新启动了，从而导致黑屏。这可能是由于您的应用程序中某些代码在重新启动时没有正确处理状态或资源释放的原因。

为了解决这个问题，您可以尝试以下几个步骤：

1. 确保您的应用程序正常退出，并释放所有占用的资源。

2. 确定您的应用程序是否正确地处理了状态。您可以尝试在重新启动应用程序之前保存应用程序的状态，以便在重新启动后还原状态。

3. 检查您的应用程序是否有任何内存泄漏或资源泄漏。这些问题可能会导致应用程序在重新启动时不稳定。

如果您仍然遇到问题，请检查您的代码和设备日志，以获取更多信息。

Table does not support optimize, doing recreate + analyze instead

在某些情况下，当你使用 `OPTIMIZE TABLE` 命令时，你可能会看到类似于“Table does not support optimize, doing recreate + analyze instead”的警告信息。这是因为 MySQL 存储引擎并不支持 `OPTIMIZE TABLE` 操作，此时 MySQL 会自动执行 `REPAIR TABLE` 以及 `ANALYZE TABLE` 操作。这个警告信息意味着 MySQL 正在执行的是重建表和分析表的操作，而不是优化表的操作。

需要注意的是，`REPAIR TABLE` 的执行可能会导致数据丢失，因此在执行该命令之前，建议先备份数据。此外，`ANALYZE TABLE` 命令用于重新计算表的统计信息，以便 MySQL 优化查询。`ANALYZE TABLE` 命令不会锁定表，因此可以在生产环境中随时执行。

Use the make_babynames_dist() function in the mdsr package to recreate the “Deadest Names” graphic from FiveThirtyEight

Sure, I understand your question. To recreate the "Deadest Names" graphic from FiveThirtyEight using the `make_babynames_dist()` function in the `mdsr` package, you can follow these steps:

1. Install the `mdsr` package by running `install.packages("mdsr")`.
2. Load the package by running `library(mdsr)`.
3. Use the `make_babynames_dist()` function to create a data frame with the distribution of names for all years between 1880 and 2018. Save the result in a variable, for example: `babynames_dist <- make_babynames_dist()`.
4. Filter the data to include only the names that were most popular in a given year, but disappeared completely in later years. To do this, you can use the `filter()` function from the `dplyr` package, like this: `dead_names <- babynames_dist %>% group_by(name) %>% filter(n() > 1 & max(year) - min(year) == n() - 1 & max(prop) == prop[1])`.
5. Plot the result using the `ggplot2` package. Here's an example code:

library(ggplot2)
ggplot(data = dead_names, aes(x = year, y = name)) +
  geom_tile(aes(fill = prop), color = "white") +
  scale_fill_gradient(low = "white", high = "darkred") +
  labs(title = "Deadest Names", subtitle = "Names that were once popular but have since disappeared completely", x = "Year", y = "Name") +
  theme(plot.title = element_text(hjust = 0.5), plot.subtitle = element_text(hjust = 0.5))

This should recreate the "Deadest Names" graphic from FiveThirtyEight using the `make_babynames_dist()` function in the `mdsr` package.
