[R] Need to understand how to troubleshoot below error
When you specify a filename such as 'housedatacomplete.csv' which has no directory path information, the file is assumed to be in the "current directory" which you can identify using the status notation at the top of the RStudio console window or using the R getwd() function. Note that we may guess something about what may be wrong if you provide that information in your request here, but it is more likely that you will need to use the operating system to investigate permissions which are really off-topic here. Your best bet will be to find a local computer tech or sysadmin to help you solve your mystery, since there can be many special configurations we on the mailing list won't know about. One note: since you are using RStudio, be sure to create a Project directory/file and do your work with a project open. That way most problems with permissions and working in the wrong directory should usually be avoided. If you cannot create a project then you definitely need local help.

[R] Need to understand how to troubleshoot below error
Hi Jeff,
im a new learner to R an I am trying to execute the below and my files get
created except for the last function write.csv(housedata, file
="housedatacomplete.csv")write where my new file housedatacomplete.csv
does not get created and no write command works for me. Also I am unable to save
any files.
setwd("C:\\Users\\Vidyut\\Desktop\\I2R")
getwd()
housesalesdata<-read.csv("housesalesdata.csv")
housefeaturesdata<-read.csv("housefeaturesdata.csv")
housedata<-merge(housesalesdata,housefeaturesdata,by="ID")
write.csv(housedata, file ="housedatacomplete.csv")
Thanks?
Meena?

[R] Need to understand how to troubleshoot below error
This looks like a case where some local tech assistance from someone familiar with Windows permissions settings would be appropriate. You may have erroneously installed R using "As Administrator" privileges, which can not only make it difficult to do anything useful but it can be difficult to completely reverse the permissions damage that has already been done. I suggest you remove R completely and in addition remove the user library directory located at C:\\Users\\Vidyut\\Documents\\R or C:\\Users\\Vidyut\\R. This may require working in As Administrator mode to succeed, which is why some local tech support might be advisable, particularly if my diagnosis is wrong. Once R is completely eradicated you should be able to install R as a normal user and give permission to install only when prompted, and avoid using As Administrator mode in the future.
