Hello,
I am a beginner and I wanted to know if there is a way to approximate a
function that has 2 input variables and one output.

I'm puzzled as to why I get this behaviour with str_split_fixed in the
stringr package.
stringr::str_split_fixed('ab','',2)
[,1] [,2]
[1,]ab
stringr::str_split_fixed('ab','',3)
[,1] [,2] [,3]
[1,]a b
In the first example, I was expecting to get
[,1] [,2]
[1,] a b

package dplyr's full_join, left_join, right_join, inner_join are also
comparable in speed to data table. The syntax is also more like merge's.

This method of finding yhat as x %*% b works when I use raw polynomials:
x-1:8
y- 1+ 1*x + .5*x^2
fit-lm(y~poly(x,2,raw=T))
b-coef(fit)

Hi,
creating a matrix from two vectors a, b by multiplying each combination can
be done e.g. via

or via

Is there an efficient way to create sparse matrices (from the Matrix
package) like that?
Right

I know that I am just leaving out some tiles in the plot, but I

Hi,
it could also be that during reading your csv the matrix became a character
matrix.
Try str(x); this should show you if your values are seen as numeric.
Also, if you have descriptive columns (e.g. date, labels, etc.) they must
be removed before calculating PCR.

I don't know the answer to your question. If nobody else answers it,
I'd suggest asking in R-devel instead, and include some simple code that
