Replace single quote with double quote in a column in R

问题

My dataframe in R has a column A where I have string data with single quote in it.

Column A
'Hello World'
'Hi World'
'Good morning world'

What I would like to do is to replace the single quote with double quotes and achieve the output like below.

Column A
"Hello World"
"Hi World"
"Good morning world

Can this be achieved? Thank you in advance for reading.

Try this:

"iris" is a sample data frame and I am trying to replace single quotes of "Species" column. Since ' and " are special characters within strings hence they are specified using escape sequences:

iris$Species <- gsub("\'","\"", iris$Species)
