I want to organize outputs from several regressions into a handy table. When I
try the following, each of my "fit_s" is replaces instead of read. Is there a
way to read from the regression summaries that does not require writing
separate lines of code for each?

fit1<-lm(dBA.spp16$sp2.dBA.ha~dBA.spp16$sp1.dBA.ha)
fit2<-lm(dBA.spp16$sp3.dBA.ha~dBA.spp16$sp1.dBA.ha)
fit3<-lm(dBA.spp16$sp3.dBA.ha~dBA.spp16$sp2.dBA.ha)
fit4<-lm(dBA.spp16$sp5.dBA.ha~dBA.spp16$sp4.dBA.ha)
fit5<-lm(dBA.spp16$sp6.dBA.ha~dBA.spp16$sp4.dBA.ha)
fit6<-lm(dBA.spp16$sp5.dBA.ha~dBA.spp16$sp6.dBA.ha)
fit7<-lm(dBA.spp16$sp1.dBA.ha~dBA.spp16$sp4.dBA.ha)
fit8<-lm(dBA.spp16$sp1.dBA.ha~dBA.spp16$sp5.dBA.ha)
dBA.spp16.fits<-matrix(NA, nrow=8, ncol=5)
colnames(dBA.spp16.fits)<-c("formula","intercept","slope","R^2","adj.R^2")
for (i in 1:8){
