### Description

Uses an Internet connection to download ECLS_K data. Data come from nces.ed.gov zip files. This function works for 1998 and 2011 data.

### Usage

downloadECLS_K(root, years = c(1998, 2011), cache = FALSE, verbose = TRUE)


### Arguments

 root a character string indicating the directory where the ECLS_K data should be stored. Files are placed in a subdirectory named ECLS_K/[year]. years an integer vector of the assessment years to download. Valid years are 1998 and 2011. cache a logical value set to process and cache the text (.txt) version of files. This takes a very long time but saves time for future uses of the data. Default value is FALSE. verbose a logical value to either print or suppress status message output. The default value is TRUE.

### Details

Beginning for the ECLS_K 2011 Study Grade 5 data files, the ChildK5p.zip source data file is a DEFLATE64 compressed zip file. This means that the user must manually extract the contained childK5p.dat file using an external zip program capable of handling DEFLATE64 zip format. As existing R functions are unable to handle this zip format natively.
