Hi,
Please help and guide. I want to cbind dataframes within the list object:
List object 'post_data' contains below sampled data frames:
post_data
$posts
from_id user_name post_msg
$comm
comm_id from_id message
$Likes
username like_id
*Note: The columns in each data frame
Hi
There are several options e.g.

http://stackoverflow.com/questions/7196450/create-a-data-frame-of-unequal-lengths
but maybe you want to do actually merging

?merge

Thanks Petr,
I'm going through the link that you have provided. Merge won't be useful in
my case. Let me give the complete picture of what I'm trying to achieve.
I'm extracting data from fb pages. I have the data frame 'pages_df' which
has all the details of the fb pages. 'Page_id' is the importan

Hello everybody,
I'm trying to harness the power of neural networks for image classification of

As for the data preparation and training of the model, everything works

Hello everyone
here is the code that implements bagging using ipred package :
library(ipred)
library(mlbench)
data("BostonHousing")
# Test set error (nbagg=25, trees pruned): 3.41 (Breiman, 1996a, Table 8)
mod <- bagging(medv ~ ., data=BostonHousing, coob=TRUE)
print(mod)
pred <- predict(mod)

Also you can specify the upper left/lower right coordinates of the legend box:
# Get the default positions/sizes
plot(1, 1)
a <- legend(x="topleft", legend = x, title = "L 1")
b <- legend(x="bottomleft", legend = y, title = "L 2")
# Use those to change the box size
plot(1, 1)
legend(x=c(a$rect$le
Forgot that I had changed the original example code:
You need this first to get the example to work:
x <- LETTERS[1:10]
y <- paste(LETTERS[1:10], letters[1:12],LETTERS[1:10])

No.

There's no way for anyone to be sure without looking directly at the code. As
Jim said, the prime suspect is inefficient use of memory and excessive use of
virtual memory.

Nobody can help you without a lot more information, though there are
some obvious places to start, like pre-allocating objects rather than
growing them inside a loop.
