Hi Mike, Please don't file bug reports without first posing such questions on R-help or R-devel first, asking if such behaviour really is a bug. (This generates extra work for the volunteers who maintain R). In this case, it's your misunderstanding of the information about three different functions on the "loadings" help page. The loadings() function is shown with one argument "x" only. The other parameters described are for the print methods also discussed on the loadings() help page. Looking at the factanal example:> # A little demonstration, v2 is just v1 with noise, > # and same for v4 vs. v3 and v6 vs. v5 > # Last four cases are there to add noise > # and introduce a positive manifold (g factor) > v1 <- c(1,1,1,1,1,1,1,1,1,1,3,3,3,3,3,4,5,6) > v2 <- c(1,2,1,1,1,1,2,1,2,1,3,4,3,3,3,4,6,5) > v3 <- c(3,3,3,3,3,1,1,1,1,1,1,1,1,1,1,5,4,6) > v4 <- c(3,3,4,3,3,1,1,2,1,1,1,1,2,1,1,5,6,4) > v5 <- c(1,1,1,1,1,3,3,3,3,3,1,1,1,1,1,6,4,5) > v6 <- c(1,1,1,2,1,3,3,3,4,3,1,1,1,2,1,6,5,4) > m1 <- cbind(v1,v2,v3,v4,v5,v6) > > > fa <- factanal(m1, factors=3) # varimax is the default > faCall: factanal(x = m1, factors = 3) Uniquenesses: v1 v2 v3 v4 v5 v6 0.005 0.101 0.005 0.224 0.084 0.005 Loadings: Factor1 Factor2 Factor3 v1 0.944 0.182 0.267 v2 0.905 0.235 0.159 v3 0.236 0.210 0.946 v4 0.180 0.242 0.828 v5 0.242 0.881 0.286 v6 0.193 0.959 0.196 Factor1 Factor2 Factor3 SS loadings 1.893 1.886 1.797 Proportion Var 0.316 0.314 0.300 Cumulative Var 0.316 0.630 0.929 The degrees of freedom for the model is 0 and the fit was 0.4755 ### Now extract just the loadings> loadings(fa)Loadings: Factor1 Factor2 Factor3 v1 0.944 0.182 0.267 v2 0.905 0.235 0.159 v3 0.236 0.210 0.946 v4 0.180 0.242 0.828 v5 0.242 0.881 0.286 v6 0.193 0.959 0.196 Factor1 Factor2 Factor3 SS loadings 1.893 1.886 1.797 Proportion Var 0.316 0.314 0.300 Cumulative Var 0.316 0.630 0.929 ### Now attempt> loadings(fa, digits = 5)Error in loadings(fa, digits = 5) : unused argument(s) (digits = 5) ### loadings() takes only one argument. ### The digits and other arguments are for the print methods, e.g.> print(fa, digits = 5)Call: factanal(x = m1, factors = 3) Uniquenesses: v1 v2 v3 v4 v5 v6 0.00500 0.10090 0.00500 0.22405 0.08429 0.00500 Loadings: Factor1 Factor2 Factor3 v1 0.94384 0.18193 0.26661 v2 0.90472 0.23484 0.15948 v3 0.23564 0.20960 0.94634 v4 0.17998 0.24225 0.82757 v5 0.24211 0.88064 0.28560 v6 0.19277 0.95884 0.19621 Factor1 Factor2 Factor3 SS loadings 1.89304 1.88576 1.79702 Proportion Var 0.31551 0.31429 0.29950 Cumulative Var 0.31551 0.62980 0.92930 The degrees of freedom for the model is 0 and the fit was 0.4755> print(loadings(fa), digits = 5)Loadings: Factor1 Factor2 Factor3 v1 0.94384 0.18193 0.26661 v2 0.90472 0.23484 0.15948 v3 0.23564 0.20960 0.94634 v4 0.17998 0.24225 0.82757 v5 0.24211 0.88064 0.28560 v6 0.19277 0.95884 0.19621 Factor1 Factor2 Factor3 SS loadings 1.89304 1.88576 1.79702 Proportion Var 0.31551 0.31429 0.29950 Cumulative Var 0.31551 0.62980 0.92930>Best Steven McKinney Statistician Molecular Oncology and Breast Cancer Program British Columbia Cancer Research Centre email: smckinney +at+ bccrc +dot+ ca tel: 604-675-8000 x7561 BCCRC Molecular Oncology 675 West 10th Ave, Floor 4 Vancouver B.C.

In 2.9.1 the documentation says
Usage:
loadings(x)
## S3 method for class 'loadings':
print(x, digits = 3, cutoff = 0.1, sort = FALSE, ...)
## S3 method for class 'factanal':
print(x, digits = 3, ...)
which indicates one argument as in the function call. The digits,
cutoff, and sort are arguments to the print methods.
(BTW, if there is a change to loadings() could it please be made a generic.)
