Age column is the first argument under Ave so if the value is NULL it will be filled by average of all the other columns presentin the below code:
#Taking care of the missing Values
dataset$Age = ifelse(is.na(dataset$Age),
ave(dataset$Age,FUN = function(x) mean(x,na.rm = TRUE)),
can you please tell me in the part FUN = function(x), how by default entire Age column ins going into variable x ? We have not declared the value to x.
There was an issue with the lab which I feel isd rectified please reach me out since it again do not workHello Pratul,
Who can help me since I do not have the laboratories available. When I give launch lab I get a blank R page and there I was following your exercises but today my exercises that I had are showing an error in addition to the fact that in the top bar it appears that I have done 0/7 projects.
Today I got lost because I keep getting an R error and I couldn't do anything.
Let me know if you need screenshots, I need to do my labs and I can't and those labs will be disabled as soon as the course finish.
I ran into that problem. The files are *.xlsx, which R doesn't really like. You can open them in excel and export them as *.csv on your machine or use an online converter. Then the read.csv should work well.Hi Pratul,
I am going through 1st project and I can't able to understand the 2 datasets in it. I see more price columns. I am assuming that price is dependent variable and rest of the attributes are independent variable. Is my assumption correct?
can you explain this datasets? do I need to merge them into single dataset for analyzing?
Thanks & Regards,
Shravan Kumar Rama
Thank you Katherine, have you started this project? I am trying to understand the requirement from 1st project.I ran into that problem. The files are *.xlsx, which R doesn't really like.

Hi! I looked at it, but chose not to do it. It needs a lot of data cleaning and it will take some regression to suggest dresses. It seemed too complicated for me right now.Thank you Katherine, have you started this project? I am trying to understand the requirement from 1st project.
This is all I got back from Support (see attached). I am still confused. What does "Q3" mean???Just to make sure I'm understanding the instructions...In Project 2, One of the directives says to...
"Provide state wise status of complaints in a stacked bar chart. Use the categorized variable from Q3."
The term "Q3" is ambiguous to me. Does it mean "Quarter 3," as in the months of the year in the third quarter, July, August and September?
OR Does it mean "Question 3," which I find more confusing because the directives are not numbered and the bulleted list is formatted strangely.
PS- Is anyone reading these??? Answers would be nice...
