get difference of non-na dates based on condition-CodePudding

Logic I am trying to build is as below

I have 4 dates columns in my table date,date1,date2,date3

if date & date1 is non-null(not blank), x=date-date1 else date & date2 is non-null, x= date-date2 else date &date3 are non-null, x = date-date3 .. where x is metric I am trying to derive.

I have tested below code in jupyter and it works fine as I was able to validate.

df$ttf <- ifelse((!is.na(df$date) & !is.na(df$date1)), df$ttf <- mondf(df$date1,df$date),
                 ifelse((!is.na(df$date) & !is.na(df$date2)), df$ttf <- mondf(df$date2,df$date),
                        ifelse((!is.na(df$date) & !is.na(df$date3)), df$ttf <- mondf(df$date3,df$date),
                               NA)))

however when I am running this job in GCP , I am getting below error

object of type 'closure' is not subsettable "

CodePudding user response：

Try this, if it brings you forward. The df$ttf <- within the ifelse should be deleted.

df <- transform(df, ttf=ifelse(!is.na(date) & !is.na(date1), date1 - date, 
                              ifelse(!is.na(date) & !is.na(date2), date2 - date, 
                                     ifelse(!is.na(date) & !is.na(date3), date3 - date, 
                                            NA))))
df
