如何在R编程中将“X”的列名与其下一列合并而无需硬编码
X 应该合并到 Day.7 X.1
应该合并到 Day.8 X.2
和 X.3 应该合并到 Day.9
代码：
library(data.table)
library(tabulizer)
pdf_file <- "new.pdf"
out2 <- extract_tables(pdf_file, pages =c(89), output = "data.frame")
out2<-as.data.table(out2)
colnames=colnames(out2)
输出：
"G" "X" "Day.7" "X.1" "Day.8" "X.2" "Day.9" "X.3"
预期输出：
"G" "Day.7" "Day.7" "Day.8" "Day.8" "Day.9" "Day.9" "Day.9"
