Hi everyone
I am new to R and have a question about missing values. I am trying to
do a cluster analysis of monthly temperatures and my data are 14 columns
with spatial coordinates (lat,lon) and 12 monthly values:
/lat - lon - temp1 - //temp2 - temp3 - .... - //temp12/
If I omit missing values (my missing values are 99.00) with
/mydata <- na.omit(mydata)/
every row with a missing value (i.e. eleven good temperature values and
one month missing) is deleted. I would like to retain all valid values
for the k-means analysis but excluding.
I've been trying and searching about na.omit, na.action, na.exclude but
can't find the right point.
Any help would be appreciated.
