--- title: "Load ILSA files" output: rmarkdown::html_vignette vignette: > %\VignetteIndexEntry{Load ILSA files} %\VignetteEngine{knitr::rmarkdown} %\VignetteEncoding{UTF-8} --- ```{r, include = FALSE} knitr::opts_chunk$set( collapse = TRUE ) ``` ```{r, echo=FALSE} library(ILSAmerge) ``` ## Check what can be loaded Using `ILSAfile.info()` we can identify different populations within an ILSA. Moreover, we can also use this information for loading an specific population into the memory. Using the 'REDS' 2021 example data provided by this package: ```{r} ILSAfile.info(inputdir = system.file("extdata/reds", package = "ILSAmerge")) ``` ## Load all information We can decide to load a population, like `BCGV1`, using `justload()`: ```{r} loaded <- justload(inputdir = system.file("extdata/reds", package = "ILSAmerge"), population = "BCGV1") ``` This will result in a list of elements loaded by `haven`, in our example, a list of 11 elements: ```{r} class(loaded) length(loaded) loaded[[1]] ``` ## Load only column information For some purposes, we might need to load only the column information, most probably to check if the attributes are correct. We can do this by setting `justattributes = TRUE`: ```{r} loaded <- justload(inputdir = system.file("extdata/reds", package = "ILSAmerge"), population = "BCGV1", justattributes = TRUE) ``` This will load all 11 datasets with 0 rows each: ```{r} length(loaded) loaded[[1]] ```
