# Why are we doing this?

### We want all of our computers to be ready to collaborate

### Package-development tools work best using recent versions of R

### To move code to/from GitHub, we need git

# Goals for this week

### R

- what version do you have? In the **R console** pane:

```r
R.version.string
```

```
## [1] "R version 3.5.3 (2019-03-11)"
```

- if you have R 3.5.3, **you're done!**

- if you have 3.4 <= R <= 3.5.2, up to you...

- if you have R < 3.4, **please update!**

--
  
- to get the latest version of R:
  - go to [https://cloud.r-project.org/](https://cloud.r-project.org/)
  - follow the *Download and Install R* link for macOS

- if you update more than a minor version, e.g. 3.4 -> 3.5, you have to reinstall your R packages

# Goals for this week

### git installation

- do you have git installed? In the **Terminal** pane:

```bash
git --version
```

```
git version 2.17.2 (Apple Git-113)
```

- if you get a response like this, **you're done!**

- if you do not get a response like this, your computer may offer to install *developer command-line tools*

- we suggest you accept the offer
  - for our purposes you need only the command-line tools, (**not all of Xcode**)
