[R] Principle Component Analysis in R

[Brett Stansfield]

Dear R 
Should I be concerned if the loadings to a Principle Component Analysis are
as follows:

Loadings:
      Comp.1 Comp.2 Comp.3 Comp.4
X100m -0.500  0.558         0.661
X200m -0.508  0.379  0.362 -0.683
X400m -0.505 -0.274 -0.794 -0.197
X800m -0.486 -0.686  0.486  0.239

               Comp.1 Comp.2 Comp.3 Comp.4
SS loadings      1.00   1.00   1.00   1.00
Proportion Var   0.25   0.25   0.25   0.25
Cumulative Var   0.25   0.50   0.75   1.00

I just got concerned that no loading value was given for  X100m, component
3. I have looked at the data using list() and it all seems OK
