[R] Check functions in package

[Kingsford Jones]

a couple more options:

> ls("package:glmnet")
 [1] "coef.glmnet"     "glmnet"          "jerr"
"nonzeroCoef"     "plot.glmnet"
 [6] "plotCoef"        "predict.elnet"   "predict.glmnet"
"predict.lognet"  "predict.multnet"
[11] "print.glmnet"
> # or
> ls(pos = 2)
 [1] "coef.glmnet"     "glmnet"          "jerr"
"nonzeroCoef"     "plot.glmnet"
 [6] "plotCoef"        "predict.elnet"   "predict.glmnet"
"predict.lognet"  "predict.multnet"
[11] "print.glmnet"

The above works because glmnet is in the 2nd position in my search list:

> search()
 [1] ".GlobalEnv"        "package:glmnet"    "package:Matrix"
"package:lattice"   "package:stats"
 [6] "package:graphics"  "package:grDevices" "package:utils"
"package:datasets"  "package:methods"
[11] "Autoloads"         "package:base"
