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
