plspm error: singular matrix 'a' in 'solve'
Hello,
I am running a simple plspm for a class project due later today and I am
receiving the following error despite following along exactly with Gaston
Sanchez's directions in PLS Path Modeling with R:
Error in solve.qr(qr(X.blok), Z[, j]) : singular matrix 'a' in 'solve'
I would greatly appreciate any help resolving this matter. I got the same

pls.pcr compared to Unscrambler
Dear R-helpers,
Has anybody ever tried to compare pls regression outputs from the pls.pcr R-package developped by Wehrens with outputs from the Unscrambler software developped by CAMO company ?

Capture of iterative integration output
Hello,
I am a novice R user and am having difficulty retrieving the values
from 21 iterations of the R function integrate.
The only way I have found is to do a write.table and then a read.table
as shown in the code below. I would rather capture the 21 values inside

error in function) so I could compute the

Assigning values based on a separate reference (lookup) table
Dear R Users,
I have a data frame of 360 rows by 720 columns (259200 values). For each value in this grid I am hoping to apply an equation to, to generate a new grid. One of the parts of the equation (called 'p') relies on reading from a separate reference table. This is Table 4 at: http://www.fao.org/docrep/s2022e/s2022e07.htm#3.1.3%20blaney%20criddle%20method (scroll down a little).
