Very BETA version - Fred Hasselman

All the functions that are required are available in scicuRe_source.R, a package will follow soon. Use the code below to source it directly from GitHub (the source function was found here). It requires you to install and load the RCurl package

source_https <- function(url, ...) {
  # load the package 
  require(RCurl)

  # parse and evaluate each .R script
  sapply(c(url, ...), function(u) {
    eval(parse(text = getURL(u, followlocation = TRUE, cainfo = system.file("CurlSSL", "cacert.pem", package = "RCurl"))), envir = .GlobalEnv)
  })
}

# Source the scicuRe_source.R toolbox!

SEARCH STRATEGY

• Need stats labelled for each experiment in a multi-experiment study
• Need measures of effect size
• Need aggregate stats, i.e. based on post-hoc power and more
• Need information to decide if proper analysis was used on stats (statcheck provides some interesting tests!)

Therefore:

• Search is implemented to be driven by the hierarchical structure of an empirical report
• Structure is: Header (e.g., Experiment 1) -> Section (e.g., Results) -> [Table 1. ->] STAT OF INTEREST <- Page number [<- Appendix]
• Extract as much information as possible!

The statcheck package bij M. Nuijten is available here
Download, unzip and install, e.g. by running:

install.packages("~/Downloads/statcheck-master/", repos = NULL, type="source")

The authors of statcheck note:

The pdftotext program (http://www.foolabs.com/xpdf/download.html) is used to convert PDF files to plain text files. This must be installed and PATH variables must be properly set so that this program can be used from command line.

For the code in this package to execute correctly pdftotxt and pdfinfo need to be available on your system as well.
Check it now:

if(all(file.exists(Sys.which("pdftotext")))) print("YES!") else print("NO!")
