x1 - c(how, to, grow, tree)
x2 - c(where, to, go, weekend, cinema)
Sorry, I forgot to mention the following: all I wrote is only valid as long
as your number of samples is smaller than the number of different words. If
the number of samples exceeds the total number of different words, you
should better use the explicit matrix representation and use some kernel

I believe you are expecting the software to do what it did not claim being able

These suggestions still require you to explicitly compute your feature

suff isn't a list, so lapply() isn't the right choice. How about instead:
suff- c(C1, C2, C3)
sapply(suff, function(x)paste(filename_, x, .ext, sep=))
C1C2C3
filename_C1.ext filename_C2.ext filename_C3.ext

Yes, there are non-vectorized functions e.g, integrate(), or you can use
lapply() to apply a vectorized function to each element of a list (which is not
what suff was) individually:
x - list(1:3, 1:4, 1:5, 2:7)
mean(x) # bad
lapply(x, mean) #good

There are, especially ones you write yourself that don't
Hello all,
I'm trying to use confint from the MASS package to compute confidence
intervals for an nls object. When I plot the results, however, they don't
make sense - lines cross over the fitted model or just don't match the
data. Code is :
Thanks for help
dat-data.frame(a,b)
with(dat,
is there a built-in synonym for
function(v) length(unique(v))
??
thanks

I require the the number at the start of each line however the text is not
needed, i am struggling to get R to import the data with out changing the
file itself?
how do i
Dear all, suppose I have a vector with elements as:
Vec - c(2,3,4,5,6)
Now I want to have all possible combination of length 3 using those
elements and without any repetition. Like, I want to have 1
possibility like 2-3-4 but not 3-2-4.
Can somebody guide me how to achieve that in R?
Thanks
Working code that normalize each row's value against the subset's maximum.
Does the invocation of max() somehow instruct R to 'step back' and evaluate
the subset?
Thanks, Zack

Just read into a data.frame with read.table and then subset to use the first
column.
e.g.,
your_desired_data - data.frame(read.table(path_to_file, sep = , fill =
T))
your_desired_data - your_desired_data[,1]

trying to switch out addresses that have double directions, such as the
following example:
a = S S Main St Interstate 95
a = gsub(pattern=S S , replacement=S , a)
the problem is that I don't want to affect instances where this might be
a correct address such as the following:
3421 BIGS St
