checkForRcompareCol
colsWithUnequalValues: a dataframe summarising a column with unequal values
collapseClasses. Collapse the classes of an object to a single string
Checks that a list of indexes areunique
function for updating a compare object with
information passed to it from the match rows function
cleanColNames : get colnames, remove leading and trailing whitespace and push to upper case
createTextSummary: create a text based summary of an dataCompareR object
coerceData
Converts the output of the column matching logic to something consumable by updateCompareObject.
matchColumns : create subset of DFA and DFB to contain matching column names for both data frames
Generates an empty list of the correct class to store results
Generate two dataframes that contain the same rows based on a two-column index
Create mismatch object
mismatchHighStop Checks if we've exceeded threshold of mismatches
createReportText: prepares text which is used in the summary report
Saves R markdown and HTML reports in the area specified by the user. Reports are called RcompareReport.Rmd (.html)
Uses knitr package to create tables in the markdown (createReportText function) and HTML report.
orderColumns: order columns by treated column names
Extract data from a dataCompareR comparison
Subsets on the variables that have a coercion.
Create a dataframe of the rows that don't match
Save a report based on a dataCompareR object
Converts cleaning info into a format consumable by updateCompareObject.
subsetDataColumns : create subset of DFA and DFB to contain matching column names for both data frames
Place to store and access the current object version.
Compare data. Wrapper for comparison functionality.
executeCoercions:
compareNames : compare the intersect of colInfoA and colInfoB and return boolean of matched columns for each data frame
isNotNull: is object not null
makeValidKeys
listObsNotVerbose
makeValidNames
Generate two dataframes that contain the same rows based on a two-column index
rcompObjItemLength: return length of an item, returning 0 if null, and handling the fact that
we might have a data frames or a vector
Round all numeric fields in a data frame
Generate two dataframes that contain the same rows based on a single index
updateCompareObject.colmatching
Adds a colMatching block to the output
Creates a list of info about the dataframe.
updateCompareObject.matches
Adds a colMatching block to the output
Generate two dataframes and returns subsets of these dataframes that have shared rows.
Printing RCompare Output
processFlow Handles the process flow for the whole package
validateData : routine to validate the input data
Compare two data frames
Create variable mismatch details
summary.dataCompareRobject
Summarizing RCompare Output
Takes the raw info for the meta block of the output
and puts it in a format usable by the updateCompareObject
function
trimCharVars: trim white spaces in character variables from an input dataframe
updateCompareObject.rowmatching
Adds a rowMatching block to the output
Create mismatch object
validateArguments
Extracts the column names only in one data frame from a table of
match information
Create variable mismatch table
print.summary.dataCompareRobject
Printing summaryRCompare Output
outputSectionHeader: creates an outputSectionHeader
Takes raw info for meta and adds it to the compare object
prepareData Prepares data for comparison in 3 stages.
1. Match columns - filter dataframes to those columns that match and summarise differences
2. Match rows - filter dataframes to those rows that match and summarise differences
3. Coerce data
Generic function for updating a compare object with
information passed to it, that has methods based on the class
of the info argument.
updateCompareObject.mismatches
Adds a colMatching block to the output
updateCompareObject.cleaninginfo
Updates cleaning info in the compare object
Check object is of class dataCompareRobject
listObsVerbose
Checks whether elements in two input data frames are equal.
coerceFactorsToChar: convert all factor type fields to characters
