[R] how to print the full name of the factors in summary?

[Jen-Chien Chang]

Hi,

I am wondering if there is a simple way to fix the problem I am having. 
For unknown reason, I could not get the full name of the factors to be 
printed in the summary. I have tried to used summary.lm as well but the 
problem still persists.

SJ$Weekday <- 
factor(SJ$Weekday,1:7,c("Mon","Tue","Wed","Thu","Fri","Sat","Sun"),ordered=T)
....
attach(SJ)
lm.SJ <- lm(Demand ~ Weekday+Month+Holiday+Season)
summary(lm.SJ)
Call:
lm(formula = Demand ~ Weekday + Month + Holiday + Season)

Residuals:
     Min      1Q  Median      3Q     Max
-69.767 -12.224  -1.378  10.857  91.376

Coefficients: (3 not defined because of singularities)
             Estimate Std. Error t value Pr(>|t|)
(Intercept)  88.7091     3.3442  26.527  < 2e-16 ***
Weekday.L    20.8132     2.8140   7.396 1.08e-12 ***
Weekday.Q   -12.7667     2.8156  -4.534 7.99e-06 ***
Weekday.C   -10.6375     2.8113  -3.784 0.000182 ***
Weekday^4    -8.3325     2.8103  -2.965 0.003238 **
---------------------------------------------

Is there a way for summary to print the full name of the factors and 
levels? Say Weekday.Tue instead Weekday.L?

Thanks!
