Hi, I was able to get the merge to work OK, I think...


Bats_weather<-merge(sewage.Wind_Temp.temp,Tabr_all2.temp,by.x="row.names",by.y="row.names",incomparables
    = NA,all.x =F,all.y =T)
> rm(list=c("sewage.Wind_Temp.temp","Tabr_all2.temp"))
> dput(Bats_weather,'C:/=Bat data
    working/Rainey/Sewage/Tadbra_weather.robj')
> Bats_weather[,9]<-as.character(Bats_weather[,9])
> dput(Bats_weather,'C:/=Bat data
    working/Rainey/Sewage/Tadbra_weather.robj')
> obj_a <- t.test(x = Bats_weather$Number,y =
    Bats_weather$Temp_E,paired = TRUE)
> print(obj_a) 

But I can not run the correlations...

> ggcorplot(cor.mat=corr.mat,data=Bats_weather,
+ cor_text_limits=c(5,20),
+ line.method="lm")
Error: cannot allocate vector of size 1.6 Gb
In addition: Warning message:
In get(x, envir = this, inherits = inh) :
  restarting interrupted promise evaluation
> rm('corr.mat')
