I have a data frame whose rows are 678013 . I would like to remove rows
from 30696 to 678013 and then attach a new column with a length of 30595.
I tried
Y<- X[-30595:678013,] and its not working
In addition how do i add a new column
Kindly assist.

I usually avoid global settings as they may change between graphs therefore

Ravi,
Take a look at the following link.

I followed the instructions to get a Windows version of the 'nix utility
program , bc (a high precision calculator), and the source for an R to bc
interface. After installing them, I executed
exp(sqrt(bc(163))*4*atan(
But not 120 bits of pi... just 120 bits of the double precision version of pi.

precedence does matter in this example. the square
root was taken of a doubleprecision (53 bit) number. my revision
takes the square root of a 120 bit number.

There is a precedence error in your R attempt. You need to convert
163 to 120 bits first, before taking
its square root.

Hello everyone.
I am trying to re-analyse some data with an R function I last used in 2011.
Everything seemed to work fine then, but now, using the same code, it gives me
this error:
Error in R.pe(y, group1, group2, returnR = FALSE) :
no slot of name "fixef" for this object of class "
Thank you so much for replying me!
for better understanding my problem, I explain my problem more:
I have a 682*1 matrix called "met" , the first 5 rows similar below:

[1] "glycine_imp"
[2] "Nacetylglycine_imp"
[3] "sarcosine_imp"
[4] "dimethylglycine_imp"
[5] "betaine
Let me rephrase my 2nd point:
simpleTheme() has a specific list of **arguments** which is nothing
like you show. As the Help says, its value is a list of parameter
settings that can be used by par.settings.

I don't know much about Rmpfr, but it doesn't look like your "pi" or "sqrt" or
"exp" are being handled by that package, so I am not really seeing why your
result should be more accurate when you have loaded that package.

Just a wild guess, but did you check exactly which operations are actually done
to high precision? Obviously you will need high-resolution representations of
pi and e to get an improved result.

Hello,
There's a difference between the displayed value and the internally stored.
You could use options(digits=10), but this is a global option, and will
affect all future numerical output. default value is 7

Hi,
Ramanujan supposedly discovered that the number, 163, has this interesting
property that exp(sqrt(163)*pi), which is obviously a transcendental number, is
real close to an integer (close to 10^(-12)).
If I compute this using the Wolfram alpha engine, I get:

Hi Jim,
Thanks,Jim. I couldn't get fread to work either for this.
I ended up with this:
txt<- readLines('test_fread.dat');
data.frame1 <- read.table(text=txt, sep='', header=FALSE,
skip=grep('*END*', txt))
BTW, i use that Map Rose function you wrote a few years back quite often.

Although Kehl and Petr have already answered the question, I would suggest

When R prints numbers, it follows various rules regarding how many decimal
places to display
Lattice's bwplot() displays and prints (using pdf()) the box.rectangle and
box.umbrella in a pale blue that is a pale gray on b&w laser printer output.
I would like to set default options so the box and whiskers are displayed
and printed in black by modifying ~/.Rprofile by adding a .First() fun
Hi Roger,
You're mixing up storage and display:
p <- "1087.003489"
p <- as.numeric(p)
> p
[1] 1087.003 # the default value for digits = 7, which can be changed
with option()
> print(p, digits=4)
[1] 1087
> print(p, digits=10)
[1] 1087.003489
But note also:
> print(p, digits=20)
[1] 1087.003488
Hi
As already mentioned it is a matter of printing result on your console.

The other problem is that when using PC you run into FAQ 7.31 decimal issue.

Hi Roger,
I think it does! Try multiplying with 100 or similar. It is just a matter
of displaying your result.

I have a string that contains a number and when I convert it to a number I
loose precision and I would like to know if there is a way to avoid that. Here
is my example:
p <- "1087.003489"
