Hello,
Try the following.
idx <- duplicated(df) | duplicated(df, fromLast = TRUE)
df[idx, ]
Note that they are returned in their original order in the df.
Hope this helps,
Rui Barradas

I would like to select a all the duplicate rows of a data frame including
the original. Any help would be much appreciated. This is where I'm at so
far. Thanks.
#Sample data frame:
df <- read.table(header=T, con <- textConnection('
label value
A 4
B 3
C 6
B 3
B 1
A 2
A 4
A 4
'))
close(con)
# Duplicate entries
df[duplicated(df),]
# label value
# B 3
# A 4
# A 4
#I want to select all the rows that are duplicated including the original
#This is the output I want
# label value
# B 3
# B 3
# A 4
# A 4
# A 4
