,可以使用以下方法:
data <- read.table("data.csv", header = TRUE, colClasses = c("character", "character", "character", "character", "character", "character", "character", "character"))
data <- read.csv("data.csv", header = TRUE, colClasses = c("character", "character", "character", "character", "character", "character", "character", "character"))
data$double_column <- as.character(data$double_column)
