This is a more detailed description of the problem,
I have written the following lines of code to read the files
data1=("c:\\mydata\\file1.txt")
data2=("c:\\mydata\\file2.txt")
NONONO. Read the manual again. Perhaps:
data1 <- read.table("c:\\mydata\\file1.txt")
data2 <- read.table("c:\\mydata\\file2.txt")
file 1 has fields like patientID, Name which are common in file2,
however
not all fields are common
i would like to create file3.txt with the merged data fields,
And what might happen happened when you tried:
merg12 <- merge(data1, data2)
??? ... by default it would merge on the field names (actually column
names in R-parlance) that were shared by the two dataframes.
