I have ADCP measured data for a river and I am wondering if it is possible
to read the ADCP file in R. I found a package called oce but I couldn't
read the ADCP file.
The function I found in oce package is as follows:
read.oce
read.adp
I have uploaded the sample file here
I've two data.tables as shown below:
***
N = 10
A.DT - data.table(a1 = c(rnorm(N,0,1)), a2 = NA))
B.DT - data.table(b1 = c(rnorm(N,0,1)), b2 = 1:N)
setkey(A.DT,a1)
setkey(B.DT,b1)
***
I tried to change my previous data.frame implementation to a
data.table implementation by changing the for-loop

Please describe what do you mean by stacking files?
Stack takes each numeric column of data frame and transform it to two column
data frame with one column being numeric value and the other column an
indicator based on column name.
see

stacking the rasters will make them as multi layers as they have the same
dimension exten ... so as one layer.
so we can do calculation with them.
