This is my data-frame to make it simple I will show only 3 column Objective
I would like to split the dataframe my 3rd column into a new column with new name "direction"
dput(head(c))
structure(list(Chemical.Name = c("Ethylnitrosourea", "Valproic Acid",
"sodium arsenite", "Tobacco Smoke Pollution", "Valproic Acid",
"Valproic Acid"), Gene.Symbol = c("A", "A1BG", "A1CF", "A2M",
"A2M", "A2M-AS1"), Interaction.Actions = c("increases^mutagenesis",
"affects^expression", "decreases^expression", "decreases^expression",
"decreases^expression", "decreases^expression")), row.names = c(1L,
8L, 13L, 36L, 42L, 44L), class = "data.frame")
My data frame looks like this
head(c)
Chemical.Name Gene.Symbol Interaction.Actions
1 Ethylnitrosourea A increases^mutagenesis
8 Valproic Acid A1BG affects^expression
13 sodium arsenite A1CF decreases^expression
36 Tobacco Smoke Pollution A2M decreases^expression
42 Valproic Acid A2M decreases^expression
44 Valproic Acid A2M-AS1 decreases^expression
So here I would like to parse the 4th column in my dataframe called c and then make a new df or add new column to it where the new column can be called directionwhich should contain term that is coming before ^ word or anything that is on the left side of this ^ which will go to the a new column under direction.
I would like to dput my patterns that exist in that third column
