Hi,
I have imported one dataset in R.
I want to calculate the percentage of missing values for each month (May
2006 to March 2007) for each variable.
Just to begin with I tried the following code :
*for(i in 1:length(dos))
for(j in 1:length(patientinformation1)
if(dos[i]=="May-06" && patientinformation1[j]=="")
a <- j+1
a*
The above code was written to calculate the number of missing values for May
2006, but I am not getting the correct results.
Can anybody help me?
Thanks,
Shreyasee
