list output truncated - How to expand listed variables with str() in R
问题 I have a data.frame df with 600+ variables. I'm writing a function that automates the creation of columns and need to visually check them once. The str function provides a good summary: str(df) 'data.frame': 29 obs. of 602 variables: $ uniqueSessionsIni: POSIXct, format: "2015-01-05 15:00:00" "2015-01-05 16:00:00" "2015-01-05 17:00:00" ... $ uniqueSessionsEnd: POSIXct, format: "2015-01-05 15:59:00" "2015-01-05 16:59:00" "2015-01-05 17:59:00" ... $ m0p0 : POSIXct, format: "2015-01-05 15:00:00"
