latex 函数latex.default 在rownames=NULL 时不使用列组参数。在我们的功能中:
if (length(rowname)) {
cx <- cbind(rowname, cx)
col.just <- c(rowlabel.just, col.just)
if (length(extracolheads))
extracolheads <- c("", extracolheads)
collabel.just <- c(rowlabel.just, collabel.just)
if (length(cgroup) == 0L)
colheads <- c(rowlabel, colheads)
else {
colheads <- c("", colheads)
cgroup <- c(rowlabel, cgroup)
rlj <- ifelse(rowlabel.just == "l", "l", "c")
cgroup.just <- c(rlj, cgroup.just)
n.cgroup <- c(1, n.cgroup)
cgroup.cols <- 1 + cgroup.cols
cline <- paste(sl, "cline{", cgroup.cols[, 1], "-", cgroup.cols[,
2], "}", sep = "", collapse = " ")
}
nc <- 1 + nc
}
使用 cgroup.cols 作为从 n.cgroup 参数计算的第一列和最后一列
first.col last.col
[1,] 1 5
[2,] 7 12
我认为这是一个错误。所以目前唯一的方法是手动编辑你的tex输出,使用这个函数,你重复你传递给你的乳胶的参数,作为你的tex file和n.cgroup的名称:
change_cline <- function(file,n.cgroup){
file_to_edit <-readLines(file)
pos <- grep("cline",file_to_edit) # get the position of cline in the tex file
cgroup.cols <- matrix(c(1,n.cgroup[2]+1,n.cgroup[1],sum(n.cgroup)+1), nrow=2)
file_to_edit[pos]<- paste("\\cline{", cgroup.cols[, 1], "-", cgroup.cols[,
2], "}", sep = "", collapse = " ")
cat(file_to_edit, file = file,sep="\n")
return(invisible(NULL))
}
最终脚本:
data(mtcars)
la<-latex(mtcars, file ='mtcars2.tex', cgroup = c("Group 1", "Group 2"), n.cgroup = c(5, 6), rowname = NULL)
change_cline(file='mtcars2.tex',n.cgroup = c(5 ,6))
生成正确的格式
