# luzlogr
Lightweight logging for R scripts.
[](https://cran.r-project.org/package=luzlogr)
## Installing
**luzlogr** is available from [CRAN](https://cran.r-project.org/package=luzlogr), and can be installed using `install.packages()`. To install the latest, developmental version from this GitHub repository:
1. Make sure you have `devtools` installed from CRAN and loaded.
2. `install_github("bpbond/luzlogr")`
Either way, you can then do:
```R
library(luzlogr)
help(package = 'luzlogr')
```
## Logging
Three functions - `openlog()`, `printlog()`, `closelog()` - provide logging of script output. They provide features including priority levels for logs and messages; optionally capturing all output (via `sink`); switching between logs; and logging to a text file or arbitrary [connection](https://stat.ethz.ch/R-manual/R-devel/library/base/html/connections.html). For example:
```R
openlog("test.log")
printlog("message")
closelog()
```
The resulting log file `test.log` looks something like this:
```
Thu Sep 17 08:46:59 2015 Opening ./test.log
Thu Sep 17 08:46:59 2015 message
Thu Sep 17 08:46:59 2015 Closing test.log flags = 0
