getting issues with using the setwd command

[MinhasMA]

Can someone comment on the setwd() command in R? Seemingly have followed the correct syntax, but keep on getting an error setwd("Addresstoworkingdirectory")

[VarunKShetty]

What is the error you get?

[MinhasMA]

Was able to figure it out. Thanks!

However, there is another issue

Quitting from lines 58-69 (MarketSegmentationProcessInClassParts1and2.Rmd) Error in file(filename, "r", encoding = encoding) : cannot open the connection

rmarkdown::render("MarketSegmentationProcessInClassParts1and2.Rmd")

What are the lines 58 - 69 in your RMD file?

[MinhasMA]

suppressWarnings(source("../../AnalyticsLibraries/library.R"))

suppressWarnings(ggthemr('fresh'))  # ggplot theme

I have the correct directory as set by setwd() But it appears that some information was lost in translation?

[VarunKShetty]

"../../AnalyticsLibraries/library.R" is a relative path. This basically says, go up two levels from the working directorry and look for a folder called "AnalyticsLibraries" at that location. Does that process make sense in your context? If not, subsitute the ../../AnalyticsLibraries/library.R with the absolute path. For example: In my case: Users/Varun/Docs/InseadAnalysticsGit/AnalyticLibraries/Library.R

[MinhasMA]

Tried it but it did not work. I looked at the folder and the analyticslibraries folder is not present in my home folder (setwd)

Could I comment out the whole section? 58-69?

[VarunKShetty]

No. Don't comment it out. The RMD needs that piece for knitting.

Do you have the Library.R script on your disk somewhere? What is the path to that file?

[MinhasMA]

Yes, file is available on my computer.

I've made the following address change (locating it to the right folder)

Still get an error

suppressWarnings(source("C:\Users\manna\Documents\COURSES\Data Science for Business\INSEADAnalytics-master\INSEADAnalytics-master\CourseSessions\Session1 /AnalyticsLibraries/library.R"))

[VarunKShetty]

Can you try this instead? I just replaced with appropriate slashes. C:/Users/manna/Documents/COURSES/Data Science for Business/INSEADAnalytics-master/INSEADAnalytics-master/CourseSessions/Session1/AnalyticsLibraries/library.R

[MinhasMA]

Tried and it still fails :(

[VarunKShetty]

Are you sure your path is correct? You should be routing to the library.R inside AnalyticsLibraries. There isn't an AnalyticsLibraries folder inside Session1 typically.

[VarunKShetty]

"C:/Users/manna/Documents/COURSES/Data Science for Business/INSEADAnalytics-master/INSEADAnalytics-master/AnalyticsLibraries/library.R" "C:/Users/manna/Documents/COURSES/Data Science for Business/INSEADAnalytics-master/AnalyticsLibraries/library.R" I think your correct path should be one of the above two.

[MinhasMA]

Thanks a lot. It works!
