Dear
R users,
We
are working on a project called,Environmental Impact Assessment. We are
stationed
at alpine regions of Ireland to see the impact of rainfall on localities. We
have
divided our study area into 92 stations. We have also collected 1 year data
from each station. Afterwards we placed data into a matrix in such a way that
we got 366*92 matrix. 366 stands for number of days.
What
we want is a lognormal probability plot, of each station(which is individual
column of matrix) with normal reduced variant on x-axis. In this way, we should
be getting, at the end, 92 curves, one for each station, on same coordinate
axis.
Kindly
help us on that. We are all very new to R.
