# not installed package names
```R
installed.pkg.names <- rownames(installed.packages())
pkg.names <- (read.table(pipe("pbpaste"), header = F, stringsAsFactors = F))$V1
not.installed.pkg.names <- setdiff(pkg.names, installed.pkg.names)

not.installed.pkg.names
 [1] "FSelector"     "RWeka"         "rattle"
```

- Package名を間違っていてInstallできていないことがあるので、ググる
- gcc, gfortran, XQuartzの設定でインストールできるようになる

Need GTK+ ? (Restart R after installing)

1: Install GTK+
2: Do not install GTK+
```

1:pkgでInstallを促されるので、brewでインストールしたものを消しておいた…

- install.packages("XML") # success
- install.packages("cairoDevice") # failしたけどOptionとしてなので放置中

### pkg-config

## FSelector
install-FSelector.R

```R
install.packages("FSelector")
also installing the dependencies ‘RWekajars’, ‘rJava’, ‘RWeka’

# より RWekaと同じ, Java関連

configure: error: Cannot compile a simple JNI program. See config.log for details.

Make sure you have Java Development Kit installed and correctly registered in R.
If in doubt, re-run "R CMD javareconf" as root.

### javareconf
- `install.packages("rJava")` のときに言われたことをする
- jenv使ってたので心配だったけど、エラーは出なかった

R-CMD-javareconf.sh
