Pull virtual study details by session info

[karissawhiting]

Currently there isn't a designated API endpoint for pulling data by virtual study ID. One way you could do this is by pulling the session info. For example:

resp <- httr::GET("https://www.cbioportal.org/api/session/virtual_study/6269715f04dc353874696f2a")
resp <- jsonlite::fromJSON(httr::content(resp, "text", encoding = "UTF-8"), simplifyVector = FALSE)
df <- resp$data

df$studies %>% unlist()

                            id                       samples1                       samples2 
"luad_tcga_pan_can_atlas_2018"              "TCGA-69-8253-01"              "TCGA-97-8174-01" 
                      samples3                       samples4                       samples5 
             "TCGA-55-6983-01"              "TCGA-67-4679-01"              "TCGA-44-6776-01" 
                      samples6                       samples7                       samples8 
             "TCGA-L4-A4E6-01"              "TCGA-78-7148-01"              "TCGA-05-4426-01" 
                      samples9                      samples10                      samples11 
             "TCGA-MP-A4TE-01"              "TCGA-80-5608-01"              "TCGA-99-8025-01" 
                     samples12                      samples13                      samples14 
             "TCGA-55-A492-01"              "TCGA-75-6206-01"              "TCGA-78-7161-01" 
                     samples15                      samples16                      samples17 
             "TCGA-62-A46P-01"              "TCGA-50-8460-01"              "TCGA-55-6971-01" 

If we were able to pull sample IDs and their corresponding study IDs in the virtual study, we could then pull data by those pieces of information.
