Sorry to prolong this thread, but I'm a bit astonished.
'bc' has been a really great tool when it was created (1975, at
Bell labs, according to Wikipedia) and made available, open
source, eventually, and I have been fond of it at the time.
On the other hand, we have had

This illustrates why you really do not want percents... (I never quite
understand why people do want them - I can understand raw counts wheh used in
teaching as a precursor to the concept of a density, but percentages is an odd
in-between sort of thing.)
Anyways, the scaling factor is the bin
Thank you.
My requirements are that simple. One table, 11 fields, of which 3 are
interesting, 30 Million records, growing daily by between 30.
And, yes I have spent an enormous amount of time reading these things,
but for someone not dealing with this professionally and/or on a daily
basis,
In what format is this growing data stored? CSV? SQL? Log textfile? You say
you don't want to use sqldf, but you haven't said what you do want to use.

Hi experts
I woul like to change my x-axis. Like this: 10,...,2,...,1
I am using this code:
r-c(1:10)
plot(r, axes=FALSE, frame.plot=TRUE,xlim=c(10,1))
axis(1,at=10/seq(1:10))
axis(2, at=axTicks(2), axTicks(2))
but my x-sxis i still: 1,..., 2,...,10
What should I do?

It's in MySQL, at the moment roughly 1.8 GB, if I pull it into a
dataframe it saves to 180MB. I work from the dataframe.
But, it's not only a size issue it's also a speed issue and hence I
don't care what I am going to use, as long as it is fast.

Hi,
Yes dplyr syntax is quite equivalent to SQL, although it is faster.
Another alternative you could consider is to use *data.table* which has a
syntax very similar to the way you select subset within a data.frame and in
terms of performance is faster (a bit) than sqldf.
You can get some idea

Without the sample size of a study (i.e., either the group sizes or the total
sample size), you cannot convert the p-value to a t-value or a t-value to a
d-value. And for studies where you have the d-value but no sample size, you
cannot compute the corresponding sampling variance. So, without
It sounds as if your underlying MySQL database is too slow for your purposes.
Whatever you layer on top of it will be constrained by the underlying database.
To speed up the process significantly, you may need to do work on the database
backend part of the process.

The dataset is not large by database standards. Even in mySQL - not known

indexes are reasonable.
What are your performance criteria for processing these

In R, all number (integer float double precision) is treated as double
precision. Therefore, it has only 16 significant figures. To achieve higher
precision, you have to use program support long integer
