Dear R Forum
I have a data frame as
beta_results = data.frame(instrument = c("ABC", "DEF", "JKL", "LMN", "PQR",
"STU", "UVW", "XYZ"),
beta_values = c(1.27, -0.22, 0.529, 0.011, 2.31, -1.08, -2.7, 0.42))
> beta_results
instrument beta_values
1 ABC 1.270
2 DEF -0.220
3 JKL 0.529
4 LMN 0.011
5 PQR 2.310
6 STU -1.080
7 UVW -2.700
8 XYZ 0.420
Through some other process, I am getting instrument names as say (which may
change each time I run this process
and hence I can't hard code it).
instru = c("JKL", "STU", "XYZ")
Now I want the subset of beta_results, (say beta_results_A) pertaining to only
instru i.e
beta_results_A =
instrument beta_values
3 JKL 0.529
6 STU -1.080
8 XYZ 0.420
I did try
beta_results_A = beta_results[instru]
or
beta_results_A = subset(beta_results, beta_results$instrument = instru]
but I guess it's failing.
Kindly guide
Regards
Katherine
