We can exclude the index columns by specifying in the c() vector with a – sign.

Syntax:

dataframe[,-c(column_indexes)]

Example:

R

# create a dataframe with 3 rows and 4 columns
data=data.frame(name=c("akash","kyathi","preethi"),
                subjects=c("java","R","dbms"),
                marks=c(90,98,78))
 
# exclude second and third column
print(data[,-c(2,3)])

Output:

[1] "akash"   "kyathi"  "preethi"
