df_90 = data.frame(
  "item" = c("item1", "item2", "item3"),
  "Jan_sale" = c(12, 14, 12),
  "Feb_sale" = c(11, 12, 15),
  "Mar_sale" = c(12, 14, 15)
)
df_91 = data.frame(
  "item" = c("item1", "item2", "item3"),
  "Jan_sale" = c(12, 14, 12),
  "Feb_sale" = c(11, 12, 15),
  "Mar_sale" = c(12, 15, 18)
)
print("Original Dataframes:")
print(df_90)
print(df_91)
print("Row(s) in first data frame that are not present in second data frame:")
print(setdiff(df_90,df_91))

Sample Output:

[1] "Original Dataframes:"
   item Jan_sale Feb_sale Mar_sale
1 item1       12       11       12
2 item2       14       12       14
3 item3       12       15       15
   item Jan_sale Feb_sale Mar_sale
1 item1       12       11       12
2 item2       14       12       15
3 item3       12       15       18
[1] "Row(s) in first data frame that are not present in second data frame:"
  Mar_sale
1       12
2       14
3       15
