Hi everyone, please check 2nd Class notes file, please note as the R extension is not supported in the comments to upload. I have made .txt file , please copy-paste the text in your r script and you can run the code that way in R studio. Enjoy.

HI Akash , below are the methods Pavan has taught us for data cleaning. Hope it helped.

#### Missing Data handling

# NA ( not available) and NaN ( not a number)
# is.na(df) - return logical vector ( for na - True , for other - False )
# is.nan(df) - to check nan values
# is.nan(df) - can not identify the NA values
# complete.cases() - check row wise if row have NA value or not
# colSums(is.na(df)) - check the NA values in variables
# na.omit(df) - remove the observations (rows with NA)

Need to check with Pavan, I think some error must have happened while uploading.

H Amar, The class is extended for one session , however there is no scheduled to be seen on the lms portal. I have raised the ticket for the same. Hope it will be resolved before Saturday.

Did you get the live class link,Piyush?

#### Pallavi Narayan Kashyap

Hii pavan. You told that there would be class on saturday (13/03/21) so that you would compensate that earlier class. I couldn't find the extension class in my class window. So can you tell me when the class is? we didn't finish our syllabus yet.

Anybody managed to attend the last class? I normally join the class via video recording due to time difference. Is there anywhere we can download the recording for the last class? I suppose last class is on 13 Mar 2021?

Nope, no link only vague promises.

@Support Simplilearn(4685) I did not receive any link in my mailbox yet.
Anyway it's mid night for me and can't join the live class.
Will the class be recorded? I would like to get the recording of the class.
