我正在运行以下代码...
#Create a list of all the files
file.list <- list.files(path="~/R/natural-language-processing/class-notes", pattern=".csv")
#Loop over file list importing them and binding them together
D1 <- do.call("rbind",lapply(file.list, read.csv, header = TRUE, stringsAsFactors = FALSE))

这是我在do.call上面的行中运行时遇到的错误。

很可能您正在尝试从工作目录而不是您在其中调用的目录中打开文件list.files。试一试
D1 <- do.call("rbind",
lapply(paste0("~/R/natural-language-processing/class-notes/",
file.list),
read.csv, header = TRUE, stringsAsFactors = FALSE))

另外,您可以将full.names参数设置为TRUEin list.files以获取完整路径:
file.list <- list.files(path="~/R/natural-language-processing/class-notes",
pattern=".csv", full.names = TRUE)
