Hello Total newbie here... I hope I read the guide properly
I have the following data.frame (I read it from a CSV file I cannot change)
names val
1 Mandy 1
2 2
3 John 2
4 2
I want to read the row number 2, but I want the first column to be “Mandy” and
not null
print (frame[2,])
2 Mandy 2
I can manipulate the data.frame once loaded
How can I fill all cell in column “names” with the previous value ?
Or is there a function that will get me the row and fill the “names” column ?
NOTA BENE: I do not want the answer, I want to find it myself but I need
guidance
If there is a function, tell me the library and I will search
If this is an algorithm, tell me generally how you would do and let me scratch
my head first 😊
Thanks Chris
