Dear all,
the exclude and constant.weights options are used as follows:
exclude: A matrix with n rows and 3 columns will exclude n weights. The the
first column refers to the layer, the second column to the input neuron and the
third column to the output neuron of the weight.

Hello thanks everyone for your help i managed to get a working function as
followed:
for(i in 2:length(list_df)){
list_df[[paste0("position_tab_",i)]][['ID']] <-
unlist(lapply(list_df[[paste0("position_tab_",i)]][['midpoint']],
function(x)
ifelse(any(abs(x - list_df[[paste0("position_tab_",i-1)
Perhaps the following will be helpful (you can ignore the warning message
here):

> y <- sample(1:5,12, rep = TRUE)

> flag <- as.numeric(abs(x-y)[n] <= 1)

Hi Kathan,
How about trying to create a *minimal* reproducible example, e.g. with a
list of two data frames, where each data frame has 5 rows,?
My guess is that there is a good chance that when you try to create such an
example, you will discover the problem yourself.
In the event that you create t

Hi Mohammad,
The plot you attached suggests that the underlying distribution may be
a mixture. Is there anything in your data that would explain this,
such as laden/unladen, uphill/downhill, different road surface?

Hi, I do not know how to post in general again, however my csv contains
around 5-250k data Points depending on vehicle/road type and pressure
exerted on geotechnical structures. I have used R to develope histograms of
said csv files and will attach such Picture to you in this mail and the csv

Thanks luke. cc hawq dev team.
I sent this email to R-devel 2 days before forwarding it to R-help, but no
one reply.
Is there any workaround? When were SIGUSR1 and SIGUSR2 sent in R? Or maybe
we should move all operations not too emergency out of signal handler?
Thanks.
On Tue, Aug 2, 2016 at
The handlers for SIGUSR1 and SIGUSR2 are really intended as an
emergency break, not for ordinary programming. These could be
rewritten to be safer but that would make them less immediate.
Followups would be more appropriate on R-devel.
Best,

Hi Gianni,
Your first example works fine, though you have unnecessary stuff in it:
strsplit("Myfile_MyArea1_sample1.txt", "_")
[[1]]

The second example doesn't work because of two things: the period is a
special character, and the fixed argument sho
Thanks very much for the help.
I ended up getting it to work with one small change:

Hi:
It's not at all clear to me what you want to do. Is each component of

combine them into one data frame? If so, then try

where c is the name of the list. (Not a good choice of name, by the
