I could marry you. This just helped me figure out how to separate a data set I've been working on for over a week!

Holy moly, this was helpful! Thank you for making this.

I have a data frame from which I need to select one particular value. The coil limbs in this d/f are Company, Stock_price and Value. I need to select the stock_price for company=“CCC”

Very helpful tutorial

How deal with empty/blank cell in a particular column of a data set in R ?

I have been trying to edit my data for an hour and this is the first video that I had success with!!! THANK YOU

Do you mind If I ask a question please

I was expecting filter based on string column. You didnt talk about it,

Thanks Lot... For Video

Thanks for the video! I have a question I haven't been able to find the answer for. What if I wanted to remove rows with certain keywords, and I have those keywords in a list in another data frame containing only those specific keyword? I need to remove the entire row for the column that contains those keywords. In this example, how would I remove all rows that have a list of 187 words, such as "good" and so on, under the column "ideal"?

Great, understendable, with normal accent - helped a lot, thanks

Just what I needed! Simple and clear! Thanks.

Hi, very good video.. I have a question.. How extract rows to a new data frame?.. Example.. extract all the rows "good" to a new data frame..

Hi

Great Vid! Can you do one on the by() function?

how can we prepare a dataframe from lets say diamonds where "cut" type is ideal, good and very good?

hELLO sir, in my dataset i have some NA in all the columns. i use na.omit but it returns 0 rows and all the columns present. secondly i took one variable such as dataset$sex to remove all NAs but then the rows is not equal to the other column rows in the main dataset and the remaining rows returns NA again because it isnt equal to the entire rows in the dataset.

my question is how do i fix this... how do i remove all the NAs and still have the same number of rows in each of the columns?

need your help thanks
