I offer one on one tutoring in R programming and Statistics. If you need help, please contact me at RstatisticsCoding@gmail.com This video shows a quick demonstration of how to use the sample function in R
This was super helpful to see in action. Thank you so much for explaining it!
5 years later, you can actually put the new variable at any location using the .before or .after argument of mutate
This isss great!!!! thanks a lot :)
Very clear explanation. Thanks for sharing
These commands are bringing error messages when I try using them on the latest versions of R and R Studio?
Hey that was so useful and powerpacked, thanks so much ! Would you please show us how to use "Case_when" in dplyr? THANK YOU !
Hi, how to filter the value, for example, start with "B"? Thanks.
Is this equivalent to pivoting in excel?
A very helpful video, thank you!!!
thanks for the video, but i was interested in filtering character variables for those that begin with specific characters or contain specific characters
If I have many character values in a column, can I filter one character from that column? or if I have a Value in a column which is combination of character and numeric (eg, LMN1) can I filter this if yes how? Thanks
Very helpful thanks mate
dataset is not on the link...
how do you filter by date?
Better explanation about it so far.
Very clear. Thank you
me ayudó para mi laboratorio, gracias!
This is the best demonstration I've seen on this! The labels (e.g. name of dataset, column name to gather...) helped immensely. Thank you so much!
You are a life saver .. Thank you Sir a lot
I still come here from time to time to remember how to do this. Thank you!
what a compact !! nice :)
Excellent
Geez, it took forever for me to understand how to do this with the documentation. Thank you for your great explanation!
thank you!!!!! can you do tidyverse as well??
Exelente video. Exactamente lo que yo necesitaba Muchas gracias
How to select a sample of numbers lying between (0,1)
I would do something like: 1 / sample(0 : 100, 10) You need to chose how many possible values you want to allow between 0-1 by changing the second value in the sample function (in this case its 100) Also, when the sample happens return 0, you will get a result of "inf" you can change these values to 0
Thank you!!
simple and understandable example thank you
awesome !!!
Thank you so much for the video. Super helpful. How do you split data rows in R? i.e, a Column called Names_department contains data like Tina Dana_Law, Finance/Mary Jones, Sales_Finn Tom. I only need a count of the department not names, so I have to split the department from the names. About 3 million unstructured data. How do I split this row by just the department values I require.
In R I think you could still use Substr() function same function works in SAS or take it in excel and use split columns or use power query
thank you for this video you have saved my life jajaajj
Thx, helped me a lot
0:17 gather() and spread() def 1:06 spread() example 2:30 gather() example
Finally a good explanation ! Thank you!
thanks buddy
Hi Adam, amazing and great lecture! Tell me, what tool do you use to add that brackets with text?
you are so good
Thank u so much, You rocks !!!
Very clear and concise.
what if you have a data set in excel with numerous columns and you got to sample in that?
Are you saying about a specific column?
Error in .f(.x[[i]], ...) : object 'Totals' not found getting this error when I type this code df %>% gather(df, Category, Totals,22:40). Any idea why?
@@nfljets37646 Thanks for the fast reply. It worked. How can write code to reference the sum of one of the values in my new column to see if this number matches my other values?
Adam, you saved my day!
this is a really nice explanation. Thank u
This always confuses me. Everytime -_- Thanks!
hi pls make more packages video and explain with relevant data table
