Hi, Running the following example from ?Predict() throws an error I have never seen before:
set.seed(1) x1 <- runif(300) x2 <- runif(300) ddist <- datadist(x1,x2); options(datadist='ddist') y <- exp(x1+ x2 - 1 + rnorm(300)) f <- ols(log(y) ~ pol(x1,2) + x2) p1 <- Predict(f, x1=., conf.type='mean') Error in paste(nmc[i], "=", if (is.numeric(x)) format(x) else x, sep = "") : cannot coerce type 'closure' to vector of type 'character' In addition: Warning message: In is.na(v) : is.na() applied to non-(list or vector) of type 'closure' Here is the output from sessionInfo() R version 2.9.0 (2009-04-17) i686-pc-linux-gnu locale: LC_CTYPE=en_US.UTF-8;LC_NUMERIC=C;LC_TIME=en_US.UTF-8;LC_COLLATE=en_US.UTF-8;LC_MONETARY=C;LC_MESSAGES=en_US.UTF-8;LC_PAPER=en_US.UTF-8;LC_NAME=C;LC_ADDRESS=C;LC_TELEPHONE=C;LC_MEASUREMENT=en_US.UTF-8;LC_IDENTIFICATION=C attached base packages: [1] grid splines stats graphics grDevices utils datasets [8] methods base other attached packages: [1] plyr_0.1.9 mgcv_1.5-5 RColorBrewer_1.0-2 nlme_3.1-94 [5] rms_2.1-0 Hmisc_3.7-0 survival_2.35-6 lattice_0.17-25 loaded via a namespace (and not attached): [1] cluster_1.12.0 Any ideas?
