Use a regex to shorten a case_when in dplyr
I have a case_when
statement that is way too long and I think could be easily shortened using a regex on the column names
Input
de<- dd %>%
#Check that Fraction is % Time Spent in Reflux
mutate(
AcidRefluxBRAVO = case_when(
ReflDay1FractionTimepHLessThan4Supine > 4.2 ~ "SupineAcid",
ReflDay1NumberofRefluxesSupine > 73 ~ "SupineAcid",
ReflDay1FractionTimepHLessThan4Upright> 4.2 ~ "UprightAcid",
ReflDay1NumberofRefluxesUpright > 73 ~ "UprightAcid",
ReflDay1FractionTimepHLessThan4Total > 4.2 ~ "TotalAcid",
ReflDay1NumberofRefluxesTotal > 73 ~ "TotalAcid",
ReflDay2FractionTimepHLessThan4Supine > 4.2 ~ "SupineAcid",
ReflDay2NumberofRefluxesSupine > 73 ~ "SupineAcid",
ReflDay2FractionTimepHLessThan4Upright > 4.2 ~ "UprightAcid",
ReflDay2NumberofRefluxesUpright > 73 ~ "UprightAcid",
ReflDay2FractionTimepHLessThan4Total > 4.2 ~ "TotalAcid",
ReflDay2NumberofRefluxesTotal > 73 ~ "TotalAcid",
ReflDay3FractionTimepHLessThan4Supine > 4.2 ~ "SupineAcid",
ReflDay3NumberofRefluxesSupine > 73 ~ "SupineAcid",
ReflDay3FractionTimepHLessThan4Upright > 4.2 ~ "UprightAcid",
ReflDay3NumberofRefluxesUpright > 73 ~ "UprightAcid",
ReflDay3FractionTimepHLessThan4Total > 4.2 ~ "TotalAcid",
ReflDay4NumberofRefluxesTotal > 73 ~ "TotalAcid",
ReflDay4FractionTimepHLessThan4Supine > 4.2 ~ "SupineAcid",
ReflDay4NumberofRefluxesSupine > 73 ~ "SupineAcid",
ReflDay4FractionTimepHLessThan4Upright > 4.2 ~ "UprightAcid",
ReflDay4NumberofRefluxesUpright > 73 ~ "UprightAcid",
ReflDay4FractionTimepHLessThan4Total > 4.2 ~ "TotalAcid",
ReflDay4NumberofRefluxesTotal > 73 ~ "TotalAcid",
ReflDayTotalFractionTimepHLessThan4Supine > 4.2 ~ "SupineAcid",
ReflDayTotalNumberofRefluxesSupine > 73 ~ "SupineAcid",
ReflDayTotalFractionTimepHLessThan4Upright > 4.2 ~ "UprightAcid",
ReflDayTotalNumberofRefluxesUpright > 73 ~ "UprightAcid",
ReflDayTotalFractionTimepHLessThan4Total > 4.2 ~ "TotalAcid",
ReflDayTotalNumberofRefluxesTotal > 73 ~ "TotalAcid",
TRUE ~ "NoAcid"
)
)
Regex to be used:
ReflDaydNumber.*Supine
ReflDaydNumber.*Upright
ReflDaydNumber.*Total
ReflDaydFraction.*Supine
ReflDaydFraction.*Upright
ReflDaydFraction.*Total
However I am not sure how to use a regex on the column names within a case_when
statement.
