DataSpace maintains a curated collection of relevant publications, which can be accessed through the [Publications page](https://dataspace.cavd.org/cds/CAVD/app.view?#learn/learn/Publication) through the app. Some publications laos include datasets which can be downloaded as a zip file. `DataSpaceR` provides an interface for browsing publications in DataSpace and downloading publication data where available.

## Browsing publications in DataSpace

The `DataSpaceConnection` object includes methods for browsing and downloading publications and publication data.


```r
library(DataSpaceR)
library(data.table)
con <- connectDS()
con
#> <DataSpaceConnection>
#>   URL: https://dataspace.cavd.org
#>   User: jmtaylor@scharp.org
#>   Available studies: 273
#>     - 77 studies with data
#>     - 5049 subjects
#>     - 423195 data points
#>   Available groups: 3
#>   Available publications: 1530
#>     - 12 publications with data
```

The `DataSpaceConnection` print method summarizes the publications and publication data. More details about publications can be accessed through `con$availablePublications`.

This table summarizes all publications, providing some information like first author, journal where it was published, and title as a `data.table`. It also includes a pubmed url where available under `link`. Related studies under `related_studies`, and related studies with data available under `studies_with_data`.  We can use `data.table` methods to filter and sort this table to browse available publications.

For example, we can filter this table to view only publications related to a particular study:


```r
vtn096_pubs <- con$availablePublications[grepl("vtn096", related_studies)]
knitr::kable(vtn096_pubs[, -"link"])

Data for a publication can be accessed through `DataSpaceR` with `con$downloadPublicationData()`. The publication ID must be specified, as found under `publication_id` in `con$availablePublications`. The file is presented as a zip file. The `unzip` argument gives us the option whether to unzip this file. By default, the file will be unzipped. You may also specify the directory to download the file. By default, it will be saved to your `Downloads` directory. This function invisibly returns the paths to the downloaded files.

Here, we download data for publication with ID 1461 (Westling, 2020), and view the resulting downloads.


```r
publicationDataFiles <- con$downloadPublicationData("1461", outputDir = tempdir(), unzip = TRUE, verbose = TRUE)
basename(publicationDataFiles)
#> [1] "causal.isoreg.fns.R"           "CD.SuperLearner.R"            
#> [3] "cd4_analysis.R"                "cd4_data.csv"                 
#> [5] "cd8_analysis.R"                "cd8_data.csv"                 
#> [7] "README.txt"                    "Westling_1461_file_format.pdf"
```

All zip files will include a file format document as a PDF, as well as a README. These documents will give an overview of the remaining contents of the files. In this case, data is separated by CD8+ T-cell responses and CD4+ T-cell responses, as described in the `README.txt`.
