当我对我的变量执行任何操作时，例如：Y<-cbind(bank)或liq <-Liq，将显示错误 bject not found 。我想，读取excel文件有问题。我使用library("readxl")和h<-read_xlsx("banks_NA.xlsx")下载数据集。
以下是有关会话和数据的信息：
`>ls(h)
[1] "Da" "Dh_a" "Dh_l1" "Dh_m1" "Dl1" "Dm1"
[7] "K" "La_a" "La_l1" "La_m1" "Lh_a" "Lh_l1"
[13] "Lh_m1" "Liq" "Ll1" "Lm1" "Mac" "Na_Da"
[19] "OtR" "OtR_a" "PrT" "Pro" "S" "S_Bl"
[25] "S_Bo" "S_S" "bank" "date" "dis" "foreign"

昨天，我做了完全相同的操作，一切都很完美。今天我决定更新R studio，现在一切都已损坏......
