Thank you very much, Rui!
The problem with your script is that data is now in a string format, while
I need to obtain a data.frame instead.
Do you really think that I cannot do anything else with this json data?
Thank you very much again

You are not wrong to expect R to not crash. However, R (as most people use it)
is not monolithic, and you have provided neither reproducible code nor
sessionInfo() with the relevant packages loaded to help anyone interested in
investigating the problem. You are the most likely person to be able
Note though that the posting guide asked you not to use the word
'crash', as your audience has no idea what you mean by it. In some of
the senses people use (e.g. when R reports an error in your code), you
should expect R to 'crash'.

Hi all,
I am trying to merge several data sets and end up with a long data
format by date time so I can run correlations and plots. I am using
Deducer as an R GUI but can just use the R console if easier.
The data sets are weather with wind speed, relative humidity and
temperatures by date
Anyone have a solution to this by now?
Unfortunately, I made some changes, and now the graphic window pops up and

Sometimes these intermittent crashes come from memory misuse, e.g., not
allocating enough scratch space. You can sometimes make those coding errors
cause more consistent problems by calling gctorture(TRUE) before running your
code.

Hi,
The data is
x - c(4,3,5);
I need to translate it to
y - c(1,2,3,4,1,2,3,1,2,3,4,5);
i.e. for each number in x, we need to generate 1:x and put it in y.
The program need to evaluate this type of calculation for millions of times in
simulation. Is there any elegant way to make this happen
x - c(4,3,5)
y - c(1,2,3,4,1,2,3,1,2,3,4,5)
all.equal(y, sequence(x))
[1] TRUE

Hi,

The only way that I can think of that would not use iteration would be to
create some type of lookup table with every possible vector you may ever

If you are happy with internal iteration then one possibility is:
