When exporting the data frame, there will be a problem that the first row is shifted to the left by one bit. The solution is as follows
Notes:
"a": is the data frame we want to adjust
The idea of the following two methods is essentially the same: extract the row names in the data frame a to become an independent column, and add it to the front of the original data frame a to become the new first column
(1) The first solution
adjustdata <- function(data) {
data <- cbind(rownames(data),data) } #自定义一个叫做adjustdata的函数，这两行代码直接照搬不用修改
a <- adjustdata (a) #a是我们要导出的数据框，对它运算一下我们刚编写的这个函数
write.table(a, file = "a.csv", sep = ",", row.names = FALSE) #最后输出文件(2) The second solution
a <- data.frame(ID=rownames(a), a) #这里的“ID”可以替换成任意名称，它的意思是你新创建的第一列的行名
write.table(a, "tax.csv", row.names=F, col.names = T, sep=",")The effect is as follows:
After doing the conversion:
