Dear list,
I am new to R and very inexperienced. Sorry for the trouble.
I have two txt files and want to merge them by taking the average.
More specifically, for example, the txt file1, with row names and column names,
consists of 238000 rows and 196 columns. Each column corresponds
to a sample.
Hi,Jim. I created two txt files as:
x.txt
id b1 b2 b3
a1 246
a2 12 NA
a3 46 NA
y.txt
idb1 b2 b3
a1 NA44
a2 22 NA
a3 122
I tried it one more time but got different z:
x-read.table(file=x.txt,header=TRUE,row.names=1,na.strings = NA)
Here is the way to read the data and convert it. Your data was a
dataframe with the first column being the id:
x - read.table(textConnection(id b1 b2 b3
+ a1 246
+ a2 12 NA
+ a3 46 NA), header=TRUE)
y - read.table(textConnection(idb1 b2 b3
+ a1 NA44
+ a2
Hi Jim,
However, the real file has 238000 row ids and 196 column ids.
How could I read the file first and then convert it to a matrix?
