Data extraction problem after importation using RODBC
...l = channel, sqtable = "Feuil1")
data
odbcClose(channel)
Then I perform an lm regression using the following code:
reg1 <-lm(data$prod~data$pri+data$cli)
summary(reg1)
Then I try to perform a gls regression because I have a correlation problem. For this I use the following code:
reg1gls <- gls(data$prod ~ data$pri + data$cli +
correlation=corAR1(form= ~data$Year), method='ML')
The problem is that after this gls regression, I have the fellowing error message :
Error in eval(expr, envir, enclos) : 'Year' object is not find
When I relplace "Year"...
