R Apply Progress: Track with pbapply

In R language, you can use the pbapply package to monitor the progress of apply functions. The pbapply package offers progress bar functions such as pblapply(), pbapply(), and pblsapply() to display the progress of apply functions.

Below is a simple example demonstrating how to use the pbapply package to view the progress of the lapply function.

# 安装并加载pbapply包
install.packages("pbapply")
library(pbapply)

# 创建一个简单的列表
my_list <- list(a = 1:10, b = 11:20, c = 21:30)

# 使用pblapply函数并传入列表和一个简单的函数
result <- pblapply(my_list, function(x) {
  Sys.sleep(1)  # 模拟计算时间
  return(mean(x))
})

In the example above, the pblapply() function is used to apply a simple function to each element in my_list and show a progress bar to indicate the running progress. In real applications, you can choose the appropriate pbapply function as needed and apply it to your data processing process.
