Long and Wide Formats: As is common with many data sets, key variables can be concentrated in one column or spread over several. Tools format of clinical and administrative hospital data, we can perform the conversion efficiently and accurately, while keeping some metadata about the codes intact, e.g. whether they are ICD-9 or ICD-10.
icd_long_data and icd_wide_data create
data.frames using all the arguments, and sets the class, whereas
as.icd_long_data and as.icd_wide_data just set the class of
an existing data.frame.

arguments passed on to create a data.frame
as.icd_long_data: Set class on a matrix or data.frame to
icd_long_data. To convert wide to long data, use
wide_to_long.
as.icd_wide_data: Set class on a matrix or data.frame to
icd_wide_data. To convert long to wide data, use
long_to_wide.
icd_long_data: Construct a data.frame, adding the
icd_long_data class.
icd_wide_data: Construct a data.frame, adding the
icd_wide_data class.
is.icd_long_data: Return TRUE if x has the
icd_long_data class.
is.icd_wide_data: Return TRUE if x has the
icd_wide_data class.
Long or wide format ICD data is expected to be in a data frame. It does not carry any ICD classes at the top level, even if it only contains one type of code, but its constituent columns may have a class specified, e.g. 'icd9'.
