multi-regression with more than 50 independent variables
...1, the coefficients will get ?NA? in the output. Is there any
limitation for the number of independent variables in multiple linear
regressions in R? I attached my dataset as well as R codes below:
mlr.data<- read.table("./multiple.txt",header=T)
mlr.output<- lm(formula = CaV ~ SHG + TrD+ CrH+ SPAD+ FlN+ FrN+ YT+
LA+ LDMP+ B+Cu+ Zn+ Mn + Fe+ K + P+ N +Clay30 +Silt30 +Sand30

Extracting the p of F statistics from lm
I need to extract the p value from a ANOVA done with lm model
fitting <- lm(var ~ group)
Sfitting <- summary(fitting)
Sfitting[10][1] gives the F value and the degrees of freedom but I am not able to get the
p value.
The function df should give a p value given a F but I am not
able to make it work.
I found only something about aov in the R help and I am not able
to make it work
