hi ,everyone
I want subtract some dataset by subset.
From the help running help(subset), ths information is
"*subset(airquality,
Day == 1, select = -Temp)* "
while I running my script written as "*g1data<-subset(errdata,
fac>12) *"
,it is wrong with the error information "*subset.default(newerrdata,
fac>12),can not find fac*"
and g1 in read from the file as shown below
*errdata<-scan("err.dat",what = list(mon=0,day=0,err=0,fac=0))*
While I changed to *g1data<-subset(errdata, errdata$fac>12)*, there
is no
error message any more but it seems that *g1data* dooes be selected.
who can help me to subset the dataset?
As per the posting guide, please post a small/simple example of a
data.frame you are trying to subset and show us the queries you are
using and what you expect to get out of it.
We'll show you where you're going wrong ;-)
