Hello,
Now the output of str() says 'dat' is a list not a data.frame. That's
why R is complaining about dimensions (lack of, in this case).

Then run the lapply()
Also, if dput(head(dat, 20)) is very big, ommit the argument

What makes you think that with 12 elements the dimensions should be 3x4? It

Hello,
I don't understand, do you want to output:
1st line: the original input line
2nd line: I want output in following format -- this line

Thanks and with
datlines - as.data.frame(inp[( grep(PRE, inp)[1]+5 ):(grep(/PRE,
inp)[1]-1)]);
I get the data as needed.
Thanks again

Dear Rxperts,
I am back to favoRite! I would need your favoR, please!
Is there a way to use read format arguments for POSIXct or strptime
from the xml file without specifying format=... in these functions? The
format of data-time values are present in the xml file as shown below.
Please see
Hi Carlos,
Thanks for your suggestions. I saw Rui's reply about the same problem using
rle. It looks very solid. I was trying replicate the same thing with gsub,
but it was not working in that way.
For example,
txt1-my name name name is micky
gsub(\\b(\\w+)\\b(\\s+)\\1\\2,,txt1)
[1]
Below are two equivalent solutions.
study_df - data.frame(course = c(rep('Mathematics', 80 + 15),
rep('Physics', 32 + 24),
rep('Biology', 18 + 29)),
A = c(rep(1, 80), rep(0, 15),
Though not exactly what you asked for, I find the output of dput() to be useful
dput(moransl, file = moransl.txt)
results in
list(Moran.I.First, structure(list(observed = 0.06988288, expected =
-0.03225806,
sd = 0.02513276, p.value = 4.822722e-05), .Names = c(observed,
expected, sd,
thanks a alot !!! I got it :)

Hello,
Try
sink(sentiment.txt)
classify_polarity(...etc...)
sink()
If this doesn't do it see

I do think this is more of a Bioconductor question -- but no worries,
they're all much nicer there than we are here and won't flame you if
you double post :-)
Best,

This is exactly what I'm looking for in my post.
An related question can be how to get an arbitrary weight, say if row1

To scrape the data from the page, you will have to explore its

Hi,
If you need the difference between two dates from the dataset,
Try this:
dat1-data.frame(DATETIME=c(1/1/2010 0:10,1/1/2010 0:20,1/1/2010
0:30),HEADER1=c(197.19,203.88,206.56),HEADER2=c(100.08,100.10,100.04))
dat1$DATETIME-strptime(dat1$DATETIME, %d/%m/%Y %H:%M)
I just tried to figure out why R does not calculate the same johansen test
statistics as eviews does:
I imported data:
sy=read.csv(sy.csv,sep=;,header=TRUE)
si=read.csv(si.csv,sep=;,header=TRUE)
merged them.
swe=merge.zoo(si,sy)
when i test swe for cointegration with the johansen test, i get
problem solved. if one adjusts in r the time span the way i did it, r really
only has data available for this time span. to the opposite in eviews. if
one sets in eviews a time span via adjusting the sample size, it still uses
the observations outside the sample size i.e. in cointegrationn tests

This question may not belong here, but I asked this on the
