Did you (or a startup script) set the environment variable R_HISTORY to be
'~/somefile'? R does not expand the tilde in this case so you need to let
the shell do it. Perhaps ~ doesn't expand for the root user. (IMO, it is
crazy to run R, or almost any other program, as root.)

hi guys,
I'm on Centos 7.6 with R 3.6 and I see this:
>
Save workspace image? [y/n/c]: y
Warning message:
problem in saving the history file '~/.Rhistory'
from strace:
rt_sigaction(SIGWINCH, {SIG_DFL, [], SA_RESTORER, 0x7fb9dd34b5d0},
{0x7fb9dc383820, [], SA_RESTORER|SA_RESTART, 0x7fb9dd34b5d
Bricks fly fine with sufficient thrust, but you have lff with a mu argument
that never gets used, so the negative log-likelihood is constant and mle()
cannot minimize it.
You need to read up on the definition of (log-) likelihood and write a proper
one for your problem.

Hello Sir,
I am learning R and its syntax and I have successfully converted
irt.item.diff.rasch into python code and pass the inputs as per the
function made in R.
In R :-
function (items)
{
ncases <- nrow(items)
item.mean <- colMeans(items, na.rm = TRUE)
item.mean[item.mean < (1/n
Dear All,
Thank you very much for helping me.. i will try my best by using all
suggestion..
thank you again.. hopefully is work.

I am analyzing animal movement pattern using levy flight pattern and want
to fit power function to observed data and estimate exponent using Maximum
Likelihood Estimation.
I am using
lff<-function(mu){1-1/mean(log(x))}
library(stats4)
mle(lff, start = list(mu = 1))
where x is the observed data.
