How to get the n (number of observations) per conditional group

$salinity==0&data$day==i]"
Can anyone help me?

troubles with logistic regression
hello everyone,
I working on the dataset for my project in class and got stuck on trying to
run logistic regression. here is my code:
data <- read.csv(file="C:/Users/fieder.data.2000.csv")
# creating subset of men
fieder.male<-subset(data,data[,8]==1)
unmarried.male<-subset(data,data[,8]==1&data[,6]==1)
# glm fit
agesq.male<-(unmarried.male[,5])^2
male.sqrtincome<-sqrt(unmarried.male[,9])
fieder.male.mar.glm<-glm(as.factor(unmarried.male[,6])~
factor(fieder.male[,7])+fieder.male[,5]+agesq.male+
male.sqrtincome,binomial(link...
