When you put the parentheses on, you are calling the function yourself before
lapply gets a chance. The error pops up because you are giving a vector of
numbers (the answer f gave you) to the second argument of lapply instead of a
function.

Lapply is not a vectorized function. It is compact to read, but it would not be
worth using for this calculation.
However, if your data frame had multiple color columns in your data frame that
you wanted to make responses for then you might want to use lapply as a more
compact version of a for

Hi all,
Simple question I should know: I'm unclear on the logic of why the sum of a
row of a data.frame returns a valid sum but the mean of a row of a
data.frame returns NA:

mean(rock[2,],trim=0)
[1] NA

I have a simple question on a loop.
The following loop works fine:

But indeed I need also that *z_t_m* varies. Let us suppose that *z_t_m* has

I am trying to convert a string to a vector, and I'm stuck!
Suppose you have a string of numbers (string) that you want to convert to a
vector (vec). I am able to split the string turning it into a list by using
strsplit, but this makes a list, which I can't seem to access the way that
I'd lik
Here are two options that might work for you given the little bit you've said:
## If its the same parameter all 30 times
## say, for example, base = 4.5 to log
for(i in 1:30) {
print(log(1:10, base = 4.5))
}
## if they are different parameters, you could try
lapply(X = c(1.3, 3, 2.2, 4, 5), FUN
Isn't it what do.call() does?

Hi Kel,
Try this:
eval(parse(text = a))
x
Many times (though certainly not all), it may be easier/cleaner to
rethink what you are doing (the step before you get a <- "x <- 2^2")
to see if there is a simpler way.
Cheers,

Hi group,
I did some searches about this very simple question. Hope someone can help
me out.
If I have the following:
a <- "x <- 2^2"
a
[1] "x <- 2^2"
How do I evaluate the expression that gets me an answer of 4? I tried the
following:
> eval(a)
[1] "x <- 2^2"
> get(a)
Error in get(a) : obj

Dear R users,
I have a very simple question and I've tried to search for the answer.
(But failed.)
there should be a function (func) that work like

"abc"
I would like to know the name of that function. Thank you very much
for your help.

Anyway, I have often wished that something like
new.mt.sample <- miceTrainSample[, -"pID50"]
would return miceTrainSample without the pID50 column. Here are three
alternative ways to do it.
# Method 1: Assign NULL to the column
new.mt.sample <- miceTrainsSample
new.mt.sample$pID50 <- NULL

In the above code, how do I delete "pID50" column to store the resulting
object without indicating column "5". The code below does the trick, but I
wish to delete the column by specifying "-pID50" instead of "5".

I nominate this for a fortune.

It's very simple to write a "binit()" function. If all you want to do

that sums x[10*i:11*i-1] (not tested and not syntactically correct).

Hello everyone,
I have a data set, and I need to bin my data using a bin width of say g(n).
Would anyone be willing to tell me how to do this in R?
Thanks
