如何修复在R中运行cro函数时出现的错误？ df1

试试

devtools:：install\u github（“gdemin/expss”）

怎么样

或者，第二个选项是运行：

df1<-read_excel('exam.xlsx')
names(df1)

[1] "HAART_reg"    "Base_CD4"     "CD4_at_12"    "diabetes"    
[5] "hypertension" "tuberculosis" "Base"         "CD412"

name\u尝试重新安装data.table和expss:
install.packages（c（“data.table”、“expss”））
name_dots <- function(...) {
dot_sub <- as.list(substitute(list(...)))[-1L]
vnames = names(dot_sub)
if (is.null(vnames)) {
vnames = rep.int("", length(dot_sub))
novname = rep.int(TRUE, length(dot_sub))
} else {
vnames[is.na(vnames)] = ""
if (any(vnames==".SD")) stop("A column may not be called .SD. That has special meaning.")
novname = vnames==""
}
for (i in which(novname)) {
if ((tmp <- deparse(dot_sub[[i]])[1L]) == make.names(tmp))
vnames[i] = tmp
}
still_empty = vnames==""
if (any(still_empty)) vnames[still_empty] = paste0("V", which(still_empty))
list(vnames=vnames, novname=novname)
}
