There's no way for anyone to be sure without looking directly at the code. As
Jim said, the prime suspect is inefficient use of memory and excessive use of
virtual memory.
The book "Advanced R" by Hadley Wickham has a very detailed and easy to
understand section on how to benchmark and optimize
rZeppelin is an R interpreter for Apache (incubating) Zeppelin. Zeppelin
is a notebook, sort of like iPython, built on top of Apache Spark.
rZeppelin makes it possible, for the first time, to create a single data/ML

rZeppelin is an R Interpreter for the Apache (Incubating) Zeppelin project.
The intention of rZeppelin is to make it possible for regular R-using
non-programmer to integrate the power of Spark, and the wide range of ML
packages available for Python and scala, into their day-to-day toolbox —

Trying to use t m to analyze tweets, you're going to experience a long stream
of issues like the one you found, which generally relate to text formatting. I
worked through them over the past few months for a project. If you email me
offline I'll try to help and share some example code.

You could include just that library in your distribution, and change the
dynamic link path using install_name_tool. I assume how to do so in detail is
beyond the intended scope of this mailing list.

The code changes a single row; that's why I said you'd have to adapt it to your
application.

You can adapt: format(as.Date(paste(Year, sep = "-", ifelse(Year %% 4 == 0,
Start, ifelse(Start > 59, Start - 1, Start))), "%Y-%j"), "%b %d”)
But 60% of the dates in your data.frame will then be wrong.

For me, it output html from rstudio complete with code etc., with no changes
except a tinker to a call to setwd(), downloading some libraries, and no other
intervention. I haven't explored the rmarkdown capabilities before, and I was
just amazed.

The only reason that *should* happen is if there's an .Rprofile in the
directory you're in when you start R.
Where *exactly* is the .Rprofile file you want loaded, what directory are you
starting from, and what does R say is the user's home directory? Did you make
*any* changes to Rprofile.site
Twitter tweets aren't a stable database. I wouldn't expect the search results
to stay stable, as tweets are retweeted, deleted, accounts are closed, privacy
settings adjusted, etc. And if there are more than 1000 results, I don't know
that twitter is internally ordered so you'd get the same set
Iâm working on a Mac so ymmv, but Iâve been running benchmarks of vanilla R
from cran vs. recompiles with different versions of gcc and R, and I see a
speedup of 20-30% vs the cran binary after recompiling with gnu 4.9. Â Its
quite distinct. Â
Each jump in gcc revision (4.7-4.8, 4.8-4.9) s
12 matches
