Hello,
I'm trying to load a workspace and I'm getting this error:
value of 'SET_ATTRIB' must be a pairlist or NULL, not a 'double'
Is there anything I can do to correct this?
Cheers,

By accident I came across the following example:
x - 1:3
y - 1:3
line(x, y) # returns:
Call:
line(x, x)
Coefficients:
[1] -2 2
While when using 1:4, it will give the more reasonable 0,1 coefficients.
I imagine this is in the way it calculate the quantiles (i.e.: a feature).

lmom is based on L-moments, which are different from ordinary moments, except
for the 1st one. It would be truly miraculous if it gave the same result as the
ordinary method of moments or maximum likelihood.
Estimates of any distributional parameter requires that the model actually fits

This is a poor approach from a usability perspective... I suggest you create
two separate functions rather than one.
However, you seem to be missing a crucial point in the use of ggplot, which
also applies to lattice graphics. These functions actually don't produce output

Hello Chel and David,
Thank you very much for providing new insights into this issue. Here is one
more question. Why does the mutate () give incorrect results here?

There is something weird going on with mutate's interaction with the scalar

Regardless, use of rowwise should be very rare, and you are definitely abusing

Hello Jeff,
Your code has given me desired results, and your advice is well taken. I agree
with you regarding the use of logical indexing for testing conditions. Thank
you so much for your time and advice.

Could you please let me know whether R software has any advantage over MATLAB
to analyze very big datasets?

I would like to rename multiple files in a directory. Filenames are read using:

Hello!
I am working through the Social Media Mining with R book and I have
something that is a bit problematic.

print(hash2_tdm)

I put five data files (example1.dat, example2.dat, example3.dat,

Hi Chel,
Thanks for the timely reply.
It works but a minor problem remains.
Here is the modified version of your code:
file_names- list.files(pattern=Sim1971-2000_Daily_)
new_names - paste(rcp45_Daily_Sim,format(seq(length(file_names)), width=3,
flag=00), .dat, sep=)
#files -
I see that a function 'format()' is used in your code.
format(c(1,5,32,100), width=3, flag=0)
[1] 1 5 32 100
formatC(c(1,5,32,100), width=3, flag=0)
[1] 001 005 032 100
I hope this helps.

Dear Erin,
For the issue of printing big data.frame, you could define a customized
`print.data.frame` in the user environment
to prevent R prints all the data. For example:
```r
print.data.frame - function(df) {
base::print.data.frame(head(df))
cat(===\n)
base::print.data.frame(tail(df))
In the code below, the last line of code does what I am trying to do; however,
I do not know the name of the variable before the user creates it, by choosing
values in Route1. So, how can I assign values to the variables individually,
when I created them using the code in lines 9-12 and

Thanks a lot for detailed clarification. It indeed is very enlightening and
will be very useful for me in future.
And your suggestion is well taken.
