Clean up of pre-processed data

Description

Clean up of pre-processed data

Usage

cleanData(raw_fix = data, removeOutsideText = TRUE,
  removeBlinks = TRUE, combineNearbySmallFix = TRUE,
  combineMethod = "char", combineDist = 1, removeSmallFix = TRUE,
  smallFixCutoff = 80, removeOutliers = TRUE, outlierMethod = "ms",
  outlierCutoff = 800, keepRS = FALSE, silent = FALSE)

Arguments

`raw_fix`	Dataframe containing the raw fixation data that were extracted with the EMreading package
`removeOutsideText`	A logical inicating whether to remove all fixations outside the text and/or screen area. The default is TRUE.
`removeBlinks`	A logical indicating whether to exclude all blinks from the data. The default (and recommended) setting is TRUE.
`combineNearbySmallFix`	A logical indicating whether to merge small fixations < 80 ms that are within 1 character space of another fixation (the small fixation will be merged with the nearby fixation). The default is TRUE.
`combineMethod`	Method for combining small fixations. Accepted values are "char" for combaining based on a distance in characters and "pix" for combining based on distance in pixels. The default is "char".
`combineDist`	Distance for combining small fixations. Small fixations will be combined only if they occur within this distance of another fixation. Based on the input to 'combineMethod' above, enter a numeric value either in number of characters or in number of pixels. The default is 1 (characters).
`removeSmallFix`	A logical indicating whether to remove any remaining fixations smaller than a certain cut-off. The default is TRUE
`smallFixCutoff`	A numerical value indiciating the cut-off for removing small fixations (the default is 80 ms). Any values smaller than this number will be removed.
`removeOutliers`	A logical indicating whether to remove outliers from the data (default is TRUE). This parameter also requires the specification of a method and cutoff for outlier exclusion (see below)
`outlierMethod`	A string indicating what type of outlier exclusion method to use. Allowed are 2 methods: "ms" for exclusion of fixations based on a number in milliseconds; or "std" for exlusion based on values that are a certain number of standard deviations above the subject's mean.
`outlierCutoff`	Numerical value that specifies the cut-off for removing outliers. If you chose "ms" in "outlierMethod", please specify a number in ms (e.g., 800). if you chose "std", please enter a number in standard deviations above the mean (e.g., 3).
`keepRS`	A logical indicating whether to keep return sweep fixations from merging (FALSE by default)
`silent`	A logical indicating whether to print output regarding merged fixations. Set to FALSE if you don't want this output (default is TRUE).
