Plotting graph for Missing values
What does you data look like? You could use 'split' and then examine the data in each range to count the number missing. Would have to have some actual data to suggest a solution.

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
