Singular Matrix 'a' in solve
...E. Hansen at http://www.ssc.wisc.edu/~bhansen/progs/ecnmt_00.html.
*Then the variable is being transformed to*
y <- lag_v(i,0)
cf <- lag_v(c,0)
lpop <- lag_v(pop,0)
linv <- lag_v(inv,0)
lgov <- lag_v(gov,0)
d1 <- lag_v(d,0)
llife <- lag_v(life,0)
yt <- tr(y)
ct <- tr(cf)
y, cf, lpop, linv, lgov, d1, llife each is in “375x1 double matrix”
yt and ct each is “300x1 double matrix”
(I use R Studio so these characteristics are stated).
*The lag_v() and tr() process is as below:*

templated use of aggregate
Dear R-help,
I have an xts data set that i have subset by date.
now it contains a date-time-stamp, and two columns (price and volume

i've been successfully using aggregate to do so in interactive use.
say the data looks as follows:
