R 跳过列表错误

Question

我有一个 'for'，它试图加载多个文件，但是，当打开这些文件中的任何一个时，它会出现以下错误：

Error: Evaluation error: zip file 'V:/Planejamento/2021/Programação/04. Abr/Balun/~$Schedule Balun 0804.xlsx' cannot be opened.

有什么方法可以让列表中的搜索和录音继续只忽略那些打开的？

代码：

for(i in i:length(arquivo_caracter)){
  master[[i]] <- data.frame(read_excel(arquivo_caracter[i], sheet = "Master", skip = 0, .name_repair = "minimal"))
  dados[[i]] <- data.frame(read_excel(arquivo_caracter[i], sheet = "Dados",skip = 1, .name_repair = "minimal"))
}

Answer 1

按照评论中的建议，tryCatch:

arquivo_caracter <- list("test1.xls","test2.xls")

for(i in 1:length(arquivo_caracter)){
  tryCatch({
   master[[i]] <- data.frame(read_excel(arquivo_caracter[i], sheet = "Master", skip = 0, .name_repair = "minimal"))
   dados[[i]] <- data.frame(read_excel(arquivo_caracter[i], sheet = "Dados",skip = 1, .name_repair = "minimal"))},
  error = function(e) {warning(paste("Couldn't open",arquivo_caracter[i]))}
  )
}

#Warning messages:
#1: In value[[3L]](cond) : Couldn't open test1.xls
#2: In value[[3L]](cond) : Couldn't open test2.xls
