Hello,
I am using Hmisc summary.formula, latex and Sweave to produce tables for
publication. Is it possible to change the formats for binary and continuous
variables? I would prefer to show 35 (10%) and 1.5 (1.2-1.8) rather than 10%
(35) and 1.2 / 1.5 / 1.8. Here is a simple example:
sex <- factor(sample(c("m","f"), 500, rep=TRUE))
age <- rnorm(500, 50, 5)
treatment <- factor(sample(c("Drug","Placebo"), 500, rep=TRUE))
s1 <- summary(~sex + age)
s2 <- summary(treatment ~ sex + age, method="reverse")
print(s1); print(s2)
Descriptive Statistics (N=500)
+-------+-----------------+
| | |
+-------+-----------------+
|sex : m| 46% (232) |
+-------+-----------------+
|age |47.22/50.31/53.37|
+-------+-----------------+
Descriptive Statistics by treatment
+-------+-----------------+-----------------+
| |Drug |Placebo |
| |(N=257) |(N=243) |
+-------+-----------------+-----------------+
|sex : m| 47% (122) | 45% (110) |
+-------+-----------------+-----------------+
|age |47.35/50.00/52.68|46.78/50.92/53.97|
+-------+-----------------+-----------------+
Thanks,
Heemun
