I insert variable with the expss function as shown below. No error
message. My question is, how to save the variable labels in the data
frame so that I can click to read the labels. Thank you.
mydata<-read_excel("data/Excel/hseinv.xlsx",na=".")
library(expss)
mydata=apply_labels(mydata,
year ="1947-1988",
inv ="real housing inv, millions $",
pop ="population, 1000s",
price ="housing price index; 1982 = 1",
linv ="log(inv)",
lpop ="log(pop)",
lprice ="log(price)",
t ="time trend: t=1,...,42",
invpc ="per capita inv: inv/pop",
linvpc ="log(invpc)",
lprice_1="lprice[_n-1]",
linvpc_1="linvpc[_n-1]",
gprice ="lprice - lprice_1",
ginvpc ="linvpc - linvpc_1")
