Re: [R] Batch importing data with respective naming
It seems that this addition works, but has created just one object
called 'peak' with all the data from those 100 files. I'd like each
file to have a corresponding object containing the data.
Thanks for your help!

[R] Batch importing data with respective naming
I'm trying to import data from 100 text files and create data frames
that reflect their numbering.
The slow way would be to do the following:
peak1 - read.table(1--peak--hist.txt, sep=,, header=TRUE)
peak2 - read.table(2--peak--hist.txt, sep=,, header=TRUE)
peak3 - read.table(3--peak--hist.txt, sep=,, header=TRUE)
...
I tried the following:
for (i in 1:100) {
peak[[i]] - read.table(paste(i,--one--hist.txt, sep=), sep=,,
header=TRUE)
}
I receive an error saying object 'peak' not found, which leads me to
believe R is trying to look in 'peak' at to whatever position 'i' has
iterated.
How can I create these data frame objects with the numbering to match
the input text files? That is to match the iterated 'i' of the loop?
Thanks for your help!

[R] Nonlinear regression help
I seek help with nonlinear regression for my data. I've run intro trouble fitting a model to my data as follows: rate_parameter stable_population 75 1996.1277 100 1623.2979 125 1362.3475 150 1164.6738 175 1014.8227 200 892.0851 225 794.1844 250 710.1489 275 639.6738 300 578.0496 325 525.4965 350 479.4752 375 440.3050 400 402.4397 The rate_parameter here will be my independent variable which affects the stable_population quantity in an agent-based simulation. I can see that the plot of this data seems to fit an exponential decay. I would greatly appreciate if someone could help me out with this task. I've found the following info on this page helpful: https://stat.ethz.ch/pipermail/r-help/2001-December/017330.html yet, still unable to grasp what I need to do.
